I mean, it kind of is. It's been abstracted certainly, and kanban was used for all kinds of project management before software but it was made by a software company that makes tools and products for programmers, who scratched their own itch first. Their initial customer base is developers because they're building on their existing Fog Bugz (and stackexchange a little bit, because of Joel), and you need to differentiate yourself more than you are.
Even based on the screenshots on your site, I'd look at that and say "I'm just going to use Trello".
I would just not bring Trello into the picture at all. Everyone who has knowledge of online management tools is going to compare you to them without your help. What you are doing is an online kanban tool for software development, with vim-like functionality in the browser.
Maybe something like "An opinionated kanban workflow for software projects". Make more out of the fact that you're doing less than your competition. You're exactly the right tool for a particular audience, play to that strength.
It may be a regional thing. Many (I'd say most, but I don't know the actual percentage) hotels in North America require a credit card, even if you're paying by cash. They will just charge the card after you leave.
Why is it "Aspie-myopia"? People with Aspergers are entirely capable of understanding that other people have different thoughts, expectations, emotions, minds. They sometimes (it's a spectrum which means that not all have the same symptoms) have difficulty understanding others' mental state from body language and other direct social clues but they understand that people have different opinions.
You are spreading misinformation, and potentially insulting people in a throw-away portion of your otherwise good point. You don't need to be on the spectrum to be myopic.
That sort of depends on your definition of "legitimate", but in my opinion, no.
I am fully aware that I make below market pay. Almost everyone (except for my developer co-ops, who I need to pay above market to be competitive in the local market) at the not-for-profit I work for does. It's not something that it hidden but our revenue comes from government money and membership fees that is best applied towards fulfilling our mandate so from a community perspective standpoint there is some degree of necessity.
There are other compensation factors though. There's some amount of profile enhancement (in a smallish pond), I've learned a ton, I get to work with a huge number of startups, I get to participate in any of the company-run events I want (and there's a lot).
To me, those are legitimate reasons for me to accept a salary under market value. But if we were a for profit the equation changes dramatically.
Salary is not the be all and end all for all (arguably most) people, and if it's within a certain percentage of market value, then other factors of compensation do make it worthwhile. Maybe you could get 10% more working in grey cubes but you wouldn't be working with those people, you wouldn't be part of a significant force in the geek culture world, and for some those trade offs are worth it.
What makes it stink for me is that I feel like PA could afford market rates, and they're not entirely because they know they don't need to be competitive in that regard, and to me that feels exploitative. They have a huge crowd of people willing to sacrifice some financial gain to be part of them, and they're going to take advantage of that.
It's reasonable from a business standpoint, I think it's even ethical, but it doesn't mean that it's a good thing.
That doesn't mean it's not real, it's certainly not above anyone at Penny Arcade to poke the hornet's nest, but there's enough indications that I think it's safe to say it's legit.
HN does have an RSS feed, there's a link (https://news.ycombinator.com/rss) in the footer. It's not identified in a link as an alternate so auto-discovery may be difficult.
