So what fills the void for the music fan?
Mog.com is a potential candidate. It's a music based blogging network. Users blog about music and connect to others who share similar tastes and interests. Mog says it helps you create pages that are an "extension of your musical soul".
The smart thing about Mog is that it recognizes that the best way to recommend other music to you is not with an algorithm, but other people, so Mog matches you up with others that it believes can help you discover new music.
Mog is an example of an interesting phenomenon that appears to be happening with community based sites. Many seem to be trying to build volume, when the secret could be to enhance the quality of the community. It's possible that two types of environments will emerge; vertical special interest sites (imagine a medical community version of Digg) and sites where volume of people matters (teen based sites where the driver is friend acquisition).
