Earlier this week App.net founder Dalton Caldwell wrote an open letter to Mark Zuckerberg. Facebook wanted to buy out his company and threatened him to take it. Facebook was planning to launch the Facebook App Center at the time and indicated that if he did not take the offer, he would feel the full force of competition from the social network.
Caldwell vowed never to build a company that depends on a platform like Facebook or Twitter again.
Now Internet mogul Marc Andreessen is stepping down from the App.net board of directors since he is on the board at Facebook too. Andreessen Horowitz partner Scott Weiss will fill in for Marc at App.net.
