An email service to help build artists' fan base

Received an email from an artist I follow who used FanBridge:

So Many Networks, So Little Time

MySpace, Facebook, Twitter, oh my! Like you, your fans are spread out across many social networks, but that doesn't mean you need to maintain every social network separately. With FanBridge, you can communicate with fans from a single location. We then track the effectiveness of each network so you know where best to spend your time.

Looks like a terrific integrated service. Have you tried this?
