Facebook

After a period of speculation, Andreessen officially joins Facebook’s board of directors alongside Mark Zuckerberg, Jim Breyer, and Peter Thiel. The official press release calls Andreessen’s venture Ning, “a complementary platform to Facebook,” rather than a potential rival. Andressen says:

Facebook is one of the most innovative companies on the Web and it’s an honor to join the board. I’m looking forward to helping the team as Facebook continues to grow.
