I ran across great tool for auto publishing content across dozens of social networks on the internet.
It is called Onlywire. The Onlywire website will auto submit your content to all the social networking sites than you choose. So with the click of a button, you can submit content to Facebook, twitter, MySpace, Bebo, Friendster, Hi5, Orkut, just to name a few."Onlywire Social Networking Auto Publishing"
