Are you using MySpace as a marketing opportunity? Martinibuster explains the advantages:
Listen ladies and gentleman, opportunity is knocking. MySpace has 2.5 times the traffic of Google. What would you do with that kind of traffic? You can quibble about how those traffic numbers were reached, but however you slice it, it's a huge honking slice of pie. Let me repeat: There is a shitload of traffic to be tapped in MySpace.
Reminds me a bit of WebGuerrilla's post on parasite SEO.
