When I get curious about my and others online presence, I do not just do the usual Google, but also Pagebull for a visual display of results. My new favorite is yoname, which quickly combs the social networking sites and blogs and then I also check pipl and wink.

Some (not librarians) are surprised by the amount of information I can gather just from a little searching!

I would like to note that I do not sign up for any of the services that sites like wink offer (the ones that say sign up so your friends can find you because I am not that big of a fool). What is not always clear even by reading their privacy policy is what you have agreed to. One of these services does not explain that when you search for an email address, it than stores that email, which probably gets harvested.
