Usability issues - Contact list

When viewing a profile what other options might be helpful. I would begin perhaps by asking on the forum why people pull up someone's profile and what would they like or expect to be able to do. The possibilities here for making increased use of social networking tools seems good. How are we organizing all of the information that is on the profile page? What is the method behind the madness? How can we keep it from just being a random accumulation of additional information? If we could determine some type of heirarchy within Moodle for the tabs that is logical it might help.
