Ooohhhh, that's gold! Love how you added gradient to comment lines - it makes things just right - and yes, now parent comments are easily identifiable, and also citations and highlights look awesome! The communities page is pure platinum, too! I think you reached absolute perfection there. One thing I would change is the Communities/Create Post/Create Community buttons themselves. No need to have gradient frame there IMO, maybe even a simple copy of Subscribed/Local/All/Moderator view would do, but that needs testing. Also, rounding the Search button in the Communities section would likely add consistency.
