A fun (?) timewaster: search for people on wikipedia.org.
Here are some results for bloggers from my blogroll:
Dude (The Dude Abides)
Erin Murphy (Inside-Out)
Lemon Curry ?
Michael Cole (bozeman-mt)
Wulfgar! (A chicken is not pillage)
Strangely enough, only one of the blogs (Chrismukkah) is famous enough to have a relevant wikipedia entry, though several entries are pretty close (e.g., Wulfgar!).
