Thanks for replying directly. I have; I've used Gerrit and Phabricator (which also does inline comment draft keeping) a lot, and I've clicked around Rietveld. I just never have seen much use for the comment draft feature; keeping comments in draft is not what I naturally do. I can see where others might like that, so it could be a nice to have (though you can also use your browser to keep draft comments). I think GitHub and to a lesser extent Phabricator have enormous UI/UX upsides over Gerrit and Rietveld, which perpetually look like internal tools that never underwent proper UX review. What's more important is that GitHub has done so much for open source software and has achieved such critical mass that a decision to not use it now starts to also shut you off from a population of developers for whom the activation energy is too high.
