About.me is one of those ideas that gave me the "Why didn't I think of that" moment. It lead me to finding and buying http://ronnie.me The .me TLD seems to be growing quickly, grab your name if it's available.
In my case, I was able to get a shorter URL ronnieroller.com vs ronnie.me. Makes it easier to say over the phone, twitter, etc.
Make sure you set up the redirects properly. Having multiple URLs that point at the same content could penalize you on search engines for duplicate content (I believe).
