I quite like the new style changes and animations. They're fast enough to not be a bother, at least for me. I'm not sure about the random animations on the photo wall, though. I do think the details should show up when you hover over them. Besides that, it's a nice feature.

All of this can be changed in the templates. If I'm in the minority for this, all this needs to be changed. But otherwise, anybody can change the border radius for avatars and make other tweaks for their own site.
