Two and a half good places to find about me are:

LinkedIn - I tend to keep this up to date since many of my friends, collegues, and associates like to network.

ZoomInfo - This is pretty cool and goes to show just how much information is available about people.

FacesBook - This is very experimental for me, even more so than normal. If you don't think social networking is going to become more important, check out this Business Week article.
