User blog comment:Dopp/New Profile Design Now Live Across All Wikis/@comment-1277243-20110818205352/@comment-1656630-20110818221715

Offering a few prompts will encourage users who aren't sure what to share about themselves to at least offer a basic introduction. And if you start editing on a new wiki, those details will carry over automatically, making it easy for people to know a little bit about who you are.

If you don't notice profiles, that's fine. But some people appreciate having a sense of who is on the other side of the computer screen -- it makes collaborating easier and more interesting.
