I don't know, I kind of like having the post count shown. It gives you a general idea of how active people are on the forums.
I also like how we can now give respect for individual posts, rather than per poster. On the other hand, I don't think keeping a running tally of how many upvotes your posts get is a good thing. It subconsciously reinforces the "appeal to authority" fallacy - 'Oh, since this guy has +1198 respect, he's probably right about everything.' Don't get me wrong, it's fine to track the total number of upvotes a poster has, but don't display it under his/her avatar.
And I second (or third, or whatever) the request for a "popular posts" feature that lists both the most heavily upvoted posts of all time, and the most recently upvoted posts.
