Agree with all of the above. Also, drop-down menus frustrate me when I misaim a mouse click, frustrate me when using a very slow computer, frustate me when Javascript is off, and are generally the spawn of Satan.

On the plus side: whee, it looks pretty and light and stuff! (The thick borders are ugly - maybe keep lime for new comments but don't change border width.) Turning karma bubbles to karma bricks was a good idea. The header and footer are good (though the two icons are too dark for many screen configurations). The "nearby meetups" section is a really, really good idea. Yay.
