This is too bad. This was a useful service. Part of the problem might have been that individual accounts were free. I would have paid for this service.
Code reviews can definitely help improve software quality, but there are somethings you have to be mindful of.
* Talk about the design before writing code - if the design is bad very few code reviews will tell the person to throw away what they have done and start again
* Break down the code review into manageable chunks - doing a code review on hundreds of changed files is really hard to maintain focus.
Great post. As one of the Windsoc developers, I obviously believe in the Unified API. Things typically tend to move too fast for standards to be developed. OAuth is the only real "standard" people are using, but even still everyone does it just a little bit different. http://activitystrea.ms/ is another great standard that very few people use.
