> Even in Phabricator, though, when you have multiple reviewers only one has to accept for it to be accepted. Oftentimes it is _more_ confusing to have multiple reviewers because you don't know who should have the final say.
Yeah, this depends on workflow. We generally send every piece of code to two reviewers but just wait for either one to accept, unless there's a particular reason that both should look at the review. This works well for us but I can see how it wouldn't work as well for people with other processes.
> The commenting system is a matter of preference, but having forgotten to "Clowncopterize" (a great demonstration of the professionalism of those who hack on Phabricator) comments, and given that they thread in email, it hasn't been a problem for me. Though I understand where you're coming from.
Yes, Phabricator's isn't perfect but it's the best of the ones I've tried, especially if everyone using it is familiar with the tool and uses it frequently (that is, you might forget to Clowncopterize once or twice ever, but then you'll know for the future). I used to use Kiln (http://www.fogcreek.com/kiln/) which had a different approach for emails – they essentially debounce emails to have a half-hour delay and coalesce any emails within that timeframe together, so you get fewer emails but don't need to submit the collection of comments explicitly. Having tried all three choices, I'd say that they're all painful in different ways and I personally prefer Phabricator's approach.
