i own a couple that haven't gone anywhere, currently i used them to teach myself various things (PHP, JQuery, etc.)

post2coast.com/posttocoast.com - was supposed to be a local site for rentals or classifieds

groovenine.com - for a buddy who likes house music, not much going on there right now

nostradumbus.com - currently teaching myself PHP on this one, i hope to set up something like onesentence.org, but for predictions of the future.

chugandgrub.com - hope to set up some kind of happy- hour/dinner/lunch/breakfast notification system
