I am not sure if many readers here know about it, but this site has profile pages. Here is my profile, for example.

A few updates worth making:

• allow you to insert your RSS feed of your blog on the page

• track all comments from a user
• allow adding additional widgets / gadgets to profile pages
• layout improvements, but I am not sure how as of yet

What updates would you like to see made? Should any of the fields be expanded? Should any of them be killed?

You can edit your profile page under the my account section of the right sidebar.
