Anyone have any cool sites they want to share?
I've got tons

One that Jess and I have been using to find and get new music is
http://www.thesixtyone.comIt's legal. You can find lots of Indie bands, some not-so-indie bands and average joe's posting their crap. Many people upload songs for people to download for free. Half of my playlist these days is comprised of music from this site.
Another site I adore is
http://del.icio.us/It isn't music based. They describe themselves as a "social bookmarking website"
I don't use the social part of it much. But it lets me keep my bookmarks on a central Web site so that my bookmarks are the same no matter what computer I use. That's nice if you're like me and have to use computers in multiple locations.
The nice thing about this is if I find a useful link I can send it to my co-workers who also use the service.
