Last fm

I’ve been discovering new social networks everyday. Here is one I find very interesting for discovering music. It has some elements of what I would see as a future sience social network (too bad that acronym is ssn, it could have been a good domain name).

Last.fm lets you discover music that is like something you already like. I think it works kind of the same way as the amazon “you might like this”feature. If enough people buy two of the same things, then when you buy one, amazon suggests the other. In this case as well, if enough people like two different artists, then when you say you like one, last.fm suggests the other.
