I really like the Profile page so I don't have much to say about it.  But there is one enhancement I've been thinking about for a long time with regard to the Facts About Me section.  I'd love to have more questions to choose from as I feel that my facts are kind of stale after all this time and some questions may not apply to everyone. For example, my favorite bands will never change so that's going to be static data about me forever.  And some people don't read so it's kind of a moot point for them as well.  I think it would be cool to have more facts from which to choose.

Also to piggyback on what LoveisJoy said, I agree about the birthday/city/state thing.  Many of us have changed our city to something slightly more vague but a reminder about posting too much private info might be a good idea.
