I do the Myspace thing, but way too many commecials. And when some "friend" post a comment that is half a page long advertising his new song, so long buddie.
My favorite is Virb, no ads, lots of music. You can put up alot more than Myspace.
No intention of ever getting on Facebook. There are more people in life I don't want to find than I do want to find.
Crackbook looks great, I'll have to do that one.
