Thing 11--Web 2.0 Award Winners

I chose last.fm to explore. http://www.last.fm/dashboard/ I don't totally get how this works yet, but I enjoyed it so far. Users can "create streaming radio stations" and listen to those others have created. Once again, I'm not hip to the lingo which is probably contributing to my non-understanding of how this site is supposed to work. But I like that I can listen to all kinds of music & see what other people like that like what I like. (Does that make any sense?) This has obvoius (to me anyway) application in libraries to assist patrons in getting music they want but can't request & discovering something new.
