Thanks for your detailed thoughts.
Peer review is already evolving. Increasingly academics discover their papers via search engines (Google, Google Scholar), and social platforms (blogs, email, arXiv, Academia.edu, Twitter). The usage of these channels as discovery channels for research shows that the metrics that drive those channels are doing a good job at expert curation - i.e. surfacing good content.
On Google Scholar, it's citation counts that drive the ranking, and therefore the discovery process. This is the "crowd review" process I talked about in the post. With social platforms, it's recommendations from friends and colleagues that drive the discovery process. This is the "social review" process I talked about in the post.
In the pre-web days, people used to walk down to their libraries to read the latest edition from a particular journal. In those days, the journals did drive a lot of the discovery process. Nowadays, pretty much all discovery of research papers happens on the web, and most of the discovery is via channels such as search, and recommendations from colleagues over social & communication platforms.
You are right to think about the incentive systems that drive different kinds of peer review. In the case of the social review process, you want to share good recommendations with your friends, not bad ones (this is why Twitter and Facebook work as discovery channels). In the case of the crowd review process, you want to cite good works that your work genuinely built on, not bad work.

My understanding is that most publications are not heavily cited, and address very specific problems. I'm curious as to how you plan on creating incentives for qualified people to review the papers in their field which focus on problems outside of their present research interests.
To give a personal example: I used to work in a research group that applied techniques of a field called geometric control theory to the problem of modeling flocks of birds. There are not that many geometric control theorists in the world, and their interests range from robotics, to circuits, to modelings schools of fish. Right now, there are journals of control theory that force their reviewers to review all submissions, regardless of their personal interests.
How do you plan on emulating that? In other words, there need to be incentives for geometric control theorists who work on modeling schools of fish to spend a few days of their time grinding through the proofs of some grad student's paper in modeling bird flocks, which he needs for his thesis.

Peer review often works the worst when a journal asks someone who's not that qualified to peer review a paper. See the comment below from billswift about an unbelievable case of peer review going wrong, where the reviewers weren't in the research area of the target article (you need to follow the links to get the full picture).
Something doesn't have to be heavily cited for it to start getting traction, just as a website, or blog post, doesn't have to get heavily linked for it to get some traction. A friend might find the paper and share it via Twitter, their blog, or Academia.edu; this is how the social review process works on Twitter and Facebook. It might sound slow: you might wonder 'won't it take ages for a paper to get traction like that?'. But in reality, when you have social platforms like Facebook and Twitter, content can be surfaced, and whip around the world, at incredible speeds. The journal peer review process, by contrast, is several orders of magnitude slower.
The web is known for having a long tail of content: lots of content that appeals to certain niches of people. It is part of the magic of the web's discovery channels that this long tail content gets routed to the niches who care about it - via search, Facebook etc. The fact that academics overwhelmingly use the web now for research discovery is testament to how good a job the web's discovery channels are doing at surfacing good content in highly niche areas.

As a researcher myself, I do not use the web as a means of content discovery. I do use google scholar, pubmed, and citeseer, but these are only useful because they restrict the search to just peer reviewed journals (and optionally patents in google scholar case).
Trying to use general web search is often far too noisy. Often times I find interesting papers on page two, three, or four of google scholar. In a general web search these same papers might be on a much later page, or perhaps buried so far that they don't come up at all.
As others have said, there is also much more to peer review than discovery. Peer review is additionally intended to help authors improve work that isn't quite up to standards. Academics do peer review for free because they recognize the value of it and because they are asked directly by the editors to do it. In your model, what would be the incentive to look for new papers and give reviews? How would you handle old versions of papers with mistakes or papers that are of insufficient quality? The peer review process currently filters these intermediate stages of paper writing. In your proposed model, you would potentially have many versions of the same paper that a user would then have to filter through, in addition to a very great many papers that are of very low standard.
The quality of content on the web and its curation is a very poor standard to compare academic literature to. Many users are happy enough to be able to filter out obvious spam pages let alone judge quality to the level needed in academics.

It's true that the papers in the indexes of Google Scholar, Pubmed, and Citeseer are peer reviewed, but what that shows me is that what is really driving the discovery process is the ranking system in those search engines: i.e. the order in which the hundreds of results for a given search query show up.
One of the drawbacks of the existing peer review process is that academics don't get credit for their reviews, nor do the reviews see the light of day for others to benefit from. I expect that there would be significantly more discussion, and reviews, of papers in the future if there was a credit system that allowed people to get credit for reviews and comments they made of papers. I think that credit system is possible and will be built.
There is an interesting question regarding the immutability of content. Right now, once you publish a paper, you can't edit it, or delete it. It's an immutable piece of content. Before the web was established, there was a line of thinking, developed by Ted Nelson, according to which the internet should evolve like that, and that a link should always work: once some content is posted, it can never be taken down. Most people are probably glad that the web developed along the lines of Tim Berners Lee's thinking, rather than Ted Nelson's, and that they are now free to edit and delete content they have posted. I think similarly people would appreciate being able to update a paper in response to a comment they have received. The author is better off, and so are subsequent readers, as they find themselves reading a more evolved and advanced paper.

Reviewers are intentionally hidden from view. The reason is to prevent social or political backlash from a poor review. In fact, it is sometimes the case that papers reviews are double blind, the reviews do not know the names of the authors either. This is also to prevent bias on the part of the reviewers. This secrecy is a positive and important part of the peer review system. Science should not be politically or socially biased.
The immutability of published works is also crucial. It routine for writers to leave out details covering in prior works. This saves immense amounts of time on both writers consumers of scientific works. However, it also means that it is crucial that all cited works be preserved forever. If a document truly goes missing, then entire lines of work become incomplete. Papers can and are infrequently withdrawn, but as far as I know, the work is not erased, but merely marked as bad.
The way updates or corrections are made is via newer papers revisiting topics. But it remains that at every step some amount of decent due diligence is done to correct errors and not clutter up the records with incomplete versions.
As great as the web is for unstructured content, you cannot easily apply it to every area, and especially not to scientific publications. There are plenty of other examples of curated sources on the web that crucial. Map systems, curated databases of restaurants, directories of people like LinkedIn and Facebook, and even Wikipedia can be counted a curated system due to its system of editors.
Scientists have always and are still free to share data, white papers, and whatever else outside the peer review system. The main reason peer review is still here is that no suitable alternative has ever been proposed that addresses all the points that peer review does. There is a push towards open access journals to benefit the world at large though.

Summary: Current peer review is not 100%; we need to think in terms of authors' motivations (tenure); try a hacker news model, possibly layered with badges-of-approval from editorial board.
The quality of peer review is only as good as the editorial board and reviewers make it -- often this is a lower standard than we expect. This article lists several extreme examples of poor practices by a (previously-)prominent publisher:
http://blog.mathunion.org/journals/?no_cache=1&tx_t3blog...
The key to shifting academic quality control away from the present archaic model is through author's motivation. The replacement needs to be a system that improves and filters incoming papers, and at the same time earns at least as much prestige for the authors who participate.
One idea is something like a combination hacker news and stackoverflow with academic articles in place of news articles / technical questions as the object of discussion. Papers can be changed in response to comments. High scores for either a paper or an author on such a site could replace the prestige granted by acceptance into a top-tier journal. Points are awarded for reviews, and researchers are respected for their scores (closer to tenure), so there is more positive motivation to review than in today's system (which is: it's rude not to review when asked).
I think that alone could work. Some academics might balk at a lack of editorial boards. Fine, let's allow some editors in the mix. An editorial board is an aggregator. They choose what content fits their filter, and may open a discussion with an author on improvements, possibly bringing in reviewers. In the end, readers will see a prestigious badge of the board's approval on high-quality articles, and there could be a page or rss feed to browse the articles meeting this standard. This can all exist on top of the hacker news / stackoverflow system, which itself could be built on top of an arXiv-like system.
Several of these ideas are motivated by thoughts from the blogs of Tim Gowers and Michael Nielsen.

I don't think the hacker news / stackoverflow model will work for research papers. People read hacker news articles because they want to keep up with what's going on in the tech community, even if it's not super related to their particular job. Researchers generally don't just read research papers for fun. Rather, they are working on their own research, and they are looking for relevant papers whose results they can use. Hence, it's critical that when they read a paper, they know they can trust the results.
I can skim an article posted on hacker news in 30 seconds and have a general idea of what the content was. I can also skim a research paper, but only if I know that the research was done well (e.g. all the proofs are correct, or the assumptions in the model made sense, or all correct variables were properly controlled in the experiment). If that stuff isn't guaranteed, the paper is useless because I don't know if I can use it for my research. And to figure out all that stuff myself would take a few days literally out of my research. Just because 10 people skimmed it, thought it sounded cool, and up-voted it does not mean the results in the paper are correct.
Other than this review aspect, I really like this product. If they can figure out a good incentivized review system, I think it will be a big hit.

You have some good points.
Perhaps reviewers could publicly vouch for an article to give it credence. Reviewers, who are also researchers, can have scores based on their own papers. If a reviewer with a high score publicly vouches for an article, that article would receive points in favor of being correct.
The most interesting time in writing a paper is when it's under review before being accepted. The process is extremely similar to debugging an app shortly before a release. Part of my motivation for the proposed design is to upgrade this to an ongoing process -- analogous to the move from rare-release desktop software to dynamic web apps. If the author cares about their paper and receives useful comments, then the paper can iterate on that feedback.
I agree that many researchers in practice hear about papers they want to read through word of mouth. For this use case, I like to compare an online platform to stackoverflow (SO), in that you most often visit stackoverflow to solve a focused problem you have, as opposed to browsing for fun (like hacker news). You get an external problem to a page (a math paper / an SO question), you check it out, and you learn what you wanted to learn, or you contribute your knowledge or ask a question. It's a mini-community around a particular idea (a paper or a question). I see this as the main use case. The analogy with hacker news was to imply that the platform could be built around links to arXiv papers in the way HN is built around external news stories (while SO is more self-contained). Like HN, it doesn't seem necessary for an author to submit their own paper to the site.
Finally, I would say that some researchers do browse for fun. I enjoy reading several mathematicians' and computer scientists' blogs, and occasionally visit mathoverflow. This would be a secondary use of the platform, but it would be fun to have a front page of popular papers, and per-topic subpages.

Hi Tyler - nice comment. Also, wonderful work on www.thecostofknowledge.com!
I agree that discovery and credit/prestige are the two key things to get right. I'm sure that the kinds of systems you're talking about, voting systems, will be part of the research discovery/credit process in the future. It works for web content, and also for very esoteric content on the web (MathOverflow etc), so it should work for research papers too.

For an example of lousy peer review, I posted this yesterday on LessWrong:
A new science journal recently published a seriously crackpot paper, this has the abstract a link for the pdf. I first heard about it from Derek Lowe, who has also written two follow-up posts. The first has a couple of links discussing how news of the paper spread, while the second includes a link to the journal making excuses for why they published it.
<blockquote> Moreover, members of the Editorial Board have objected to these papers; some have resigned, and others have questioned the scientific validity of the contributions. In response I want to first state some basic facts regarding all publications in this journal. All papers are peer-reviewed, although it is often difficult to obtain expert reviewers for some of the interdisciplinary topics covered by this journal. I feel obliged to stress that although we will strive to guarantee the scientific standard of the papers published in this journal, all the responsibility for the ideas contained in the published articles rests entirely on their authors. </blockquote>
I included the links to all of Derek Lowe's posts because they have other interesting links, including in the comments.

Fascinating example of peer review not working out. It reminds me of the Sokal hoax, except that this one doesn't look like a hoax.

Though in a way the differences between peoples descriptions and views are details mostly, as what is clear is that peer review will change, and that it will move away from publisher-control.
Imho the biggest difficulty will be the social aspect; breaking the feedback-loop between journal-publications and perceived academic credit. Because until individual scholars can escape from the social trap of journal-publishing & handing over their copyrights, without harming their careers, they will be unlikely to do so.

Wybo - thanks for these links. I totally agree that breaking the feedback loop you mentioned, that binds academics to the current journal system, is key. I think the central things that needs to happen are: building an alternative discovery system (already happening with the web), and building an alternative credit system (happening with citation counts, and other metrics, but is lagging behind the growth in alternative discovery systems, and needs to be accelerated).
I wonder if a distributed algorithms, as used in web based currencies (eg. bitcoin) or incentive based systems (eg. bit torrent), can be adapted to the peer review system? The currency being traded would be academic credit.
I think it is not possible to achieve the quality of a peer review by "crowd review" or "social review". While most of the people are able to rate a funny picture or an interesting article on Internet, the review of an academic paper requires much more expertise in the field and knowledge of the related work. Therefore I don't believe that a truly objective rating can be created. Also, making a peer review is time consuming because you have to really understand the paper in detail and think about if the contributions are big enough and well explained, if the experiments are done properly and if the comparisons are fare and so on. This is not an easy thing to achieve by just throwing a lot of people on it (the users of the Internet).
Furthermore, when a paper is published in a well recognized journal or conference one has a guarantee of the quality of the paper. For example when I see something published at CVPR (Conference on Computer Vision and Pattern Recognition) I know it is certainly worth reading. I don't want to imagine how much more difficult it will be to find the valuable papers among all the bad stuff that is being submitted for review and rejected.
I don't want to say that the peer review process is perfect, but if I have to choose between "peer review" and "crowd review" I choose the former.

Academics have always based reading decisions on recommendations from colleagues. This trend has accelerated since email and the web were invented, as your colleagues can communicate with you through more channels, and more recommendations go back and forth. Social review always has been a big part of research discovery, and it's become more important with the advent of the web.
Search engines play a huge role in driving research discovery, and their ranking systems are fundamentally based on crowd review - calculations using links, as in the case of Google and Bing, or citations, as in the case of Google Scholar.
One might wonder in theory whether a search engine could do a good job of ranking academic papers, or whether recommendations from one's colleagues is a viable way of discovering papers. But when you look, in practice, into how academics operate day to day, those channels are the ones that academics increasingly use to discover research.

It's also worth noting that academia.edu is a for-profit enterprise. The domain academia.edu was purchased prior to the strictures put in place to ensure that only qualified educational institutions could register .edu domains, and has been grandfathered ever since. Academia.edu itself launched in 2008 apparently.
The author of this piece very much has a horse in this game, and as a result I very much view his writing with a skeptical eye.
There are serious and substantial problems with social models of publishing, especially when organizations/institutions start tying promotions and/or remuneration to metrics like impact factor (which itself is a proprietary formula).
We should keep in mind to reward good science because it's good science, not just because it's popular.

There are serious and substantial problems with social models of publishing, especially when organizations/institutions start tying promotions and/or remuneration to metrics like impact factor (which itself is a proprietary formula).

I think you are getting the horse and the cart in the wrong order (to continue the horse analogies :) ). I started Academia.edu, after finishing my PhD at Oxford, because I believe that science, is too closed, and too slow, and that I think that we can build a faster, cheaper, and better system for disseminating research. You're wondering whether I'm asserting the things in the post because I started the company, but really it's the other way round. I started the company because I believe the philosophy expressed in the post. One has to be the change one wants to see in the world.
I'm sad to see that someone downvoted factual information provided about you and the post you wrote.
And I'm not asserting anything about your motivations for why you started a for-profit company. I agree with you that the publishing models we have currently are broken. At the same time, I'm not entirely happy with some of the changes that have taken place in the past 5-10 years.
When you look to the changes that digital distribution have wrought in industries like the news media over a similar time span, the changes are not all healthy ones either from the perspective of publishers or consumers. The fact that HuffPo and Gawker have risen to the top of the pile as the sorts of money making enterprises is not such a great example to set.
Moreover, I'm unconvinced that adding more eyeballs to papers is going to improve quality of review. If your assertion is that we can make scientific review faster and cheaper without a subsequent loss of quality (let's just say "more scalable"), then I'd love to hear your response to a claim i like to make. I'd assert that publishing scientific papers is more similar to the trials and travails of online media than it is to publishing source code.
The thing that makes open source software work is that software behavior (broadly speaking) is verifiable. I can run your code and we can agree on the results, or you can tell me i'm an idiot for not configuring the software appropriately. I'd assert that FOSS scalability derives from this ability. More eyeballs helps because everyone is working from/over the same artifact.
The same can't be said for most academic papers, because most academes don't even publish their raw data, let alone possess have the facilities or the will to publish verifiable algorithmic processes for arriving at their data.
I'd love to see a project which encouraged better replicability and verification of results/test data. But you haven't suggested any of those things.
P.S. absolutely, please do be the change you're looking for. But I'm not convinced that you're the change i'm looking for.

The drawbacks of the Two Person review process are that it is [...] expensive: $8 billion a year is spent on subscriptions to journals, which is money that could be spent on more research.
None of that money goes to the two reviewers. The reviewers could do the same work for open access journals, and they would have (IMHO) no motivation not to do it for free.

Am I the only one that finds it ironic that TechCrunch is writing about peer review?
The web's "curation" works (to whatever degree it does) because there are thousands, if not millions of people who can rate the quality of most articles/essays/websites. But in many scientific fields, there are often only a very small number of people who would be qualified to review a particular paper (usually well under a hundred, sometimes as few as a handful).
And make no mistake, this is a numbers game -- there's the well known 100/10/1 rule for content websites (for every 100 viewers, there are 10 who rate content, and only 1 who creates content). The exact numbers vary quite a bit from website to website, but the point is that it's orders of magnitude difference. That's all fine if your initial pool of people is huge, but if you start with 20 qualified people...you see the issue.
Another related point not addressed is that peer review is fairly demanding work. You're not just saying "accept" or "reject", but you're obliged to write a page or two suggesting the strong and weak points of the paper, things to improve, etc. You need some mechanism for enforcing this (even if it's via social norms), otherwise review quality deteriorates quite severely, which in turn affects paper quality.
In lieu of this article, I'd recommend seeing lectures by (or essays by) Michael Nielsen, who's thought about this problem in much more detail and (I believe) has a much better understanding of the way things work.
