Having a table would be very useful. It'd be great to use it when you're telling your friends list or favorite foods on your profile.
Another tag is a button. On your profile, you can make a button and when youp pressit, a javescript alert can come up.
I'd like those two (2) tags.

One that rounded the corners on you info/bio/comments would be cool. Maybe one that had your background image stay in the same place, so the only thing that moves when you scroll is you info/bio/comments, not the background. One that changed the color of the scrollbar would be cool, but I don't think that's possible.
