Seconded! Everything about Last.fm started to detereorate from the moment they were bought by CBS. One thing in particular was baffling to me. It seemed like they deliberately tried to deemphasize the community aspects of the site. The weekly computed list of musical neighbours which used to be a great source for music discovery, got burried. Related journals and groups disappeared from artist and tag pages. In short everything that made me want to engage with other users. As a consequence, I began to visit the site less and less frequently. Because after all there is a limit to how interesting it is to look at compiled statistics about the music you listen to.
