Thanks for the shout-out to Reviewable! You mention at the end that it's only a good solution if you can adopt it wholesale, which is unfortunately true. I spent a lot of time trying to figure out how to better integrate it into a mixed Reviewable / GitHub workflow, but GitHub's comments API makes it really difficult. For example, comments must be positioned against GitHub's diff (rather than a line in a specific file revision), and commit comments disappear from the PR without a trace if their commit is rebased.<p>I agree that having something like Gitique or (even small parts of) Reviewable built right into GitHub would be ideal. My impression, though, is that GitHub is constrained by legacy data structures and assumptions, and lacks the motivation to overcome this because the tool works fine for their workflow.
