I was actually shocked two weeks ago when I was talking to someone about Gerrit and they complained that their comments were never addressed. Turns out they hadn't been hitting the "Publish Comments" button, and had been assuming that every draft comment they left was being sent as an individual email.

This taught me (or reminded me of) two things:

* GitHub is so dominant that even its poor decisions are being enshrined as "the way things work"

* Gerrit really needs some UI love as well.
