I own over 200; I guess the real question is what am I doing with them? I intended to at least make use of some of the sites I didn't have definite ideas for as self-populating blogs and park the rest at a place like Sedo. So far, all I've done is put a few at Sedo- and I haven't seen much type in traffic or revenue yet.

Having 100+ domains woudl be to heavy for me, how do you guys manage that?
