I think the new site design is generally fine, but why have the photo descriptions disappeared when you view someone's profile? You can still see your own ones but it seems other users can't, which doesn't seem very helpful as I know I used the description box to do just that: add some description to the photo where needed.
I feel awful saying it, but I'm not keen on the new site design; IMHO I think it doesn't look as pro as the previous design, and also looks dated. Some of the changes are for the better, I just feel the design side let's it down.
Personally, I like it. Though not any massive updates to functionality, the small tweaks are great improved and appreciated. E.g. The drop down menu's when you hover over them, once you bring your mouse off the link, the drop down hides, which it didnt before, it used to stay there until you hovered over another link. Which is a great improvement.
The general layout yes is "prettier", and surely thats an update in itself? Making the whole experience and user interactivity more aesthetically pleasing...
I dont think I have explored all the updates yet, but from what I can see, much better all round.
