I don't know about anybody else - but I'm liking the tweaks made to the forum recently. The changes to the menu structure that allow you to drill down into menu options without forcing you to load an "interim page" in order to get there definitely speeds things up.
The alternating gray and white shading of posts seems to make things a little easier on the eyes.
While the new formats are certainly different than the old forums - I'm getting used to 'em. The consistent (and decent performance!) is definitely making a difference.
