One of the Google Summer of Code students has been working on improving WordPress.org profiles for the past few weeks:
http://make.wordpress.org/meta/tag/profiles/

As part of his project, he wanted to add gamification aspects to the profiles (see the badge at the bottom right of the wireframe). He had to limit the scope of his project so he chose to work on improving the Profiles homepage. But once Profiles really collect all the data from our Trac / plugin / theme / support activity, I'm guessing it's going to be easier to add badges and other fancy modules to make the Profile pages sexy again!
