This is interesting to me as the great divide between myspace and Facebook in large part revolved around people no longer visiting profiles often, and instead just getting stuff fed to them in a single feed. It would be cool to have some enhanced control over profile though to mark things like..

- favorite X other accounts, with short lavels (e.g. cool dev, great wine maker, zapper)

- top X notes (I wrote or others)

- full color controls for the profile view of background, text, links and, background image with sane defaults
