"In Facebook, Investing in a Theory", NY Times
"Thousands of software developers are creating features for Facebook, the rapidly growing social network, many hoping to strike it rich alongside Facebook's own employees."
We go even further... Users of our social web applications can use many already developed widgets, applications, and content (vids, images, text) to automagically apply on facebooks. Users/members are authenicated on login. All content is RSS/XML enabled.
On a different note... If MS gets involved with facebook, they would most likely scare off (me) many of the independent developers.
