In yesterday's LA Times profile of Marc Andreessen, the mid-1990s wunderkind Netscape founder, there's one small detail about Andreessen and Gina Bianchini, his current business partner in social network Ning, that not everyone in the Valley may know:

[Andreessen] also joined the board of Harmonic Communications, a software company that tracked and measured advertising. [Sequoia Capital VC Mark] Kvamme introduced him to Bianchini, a former Goldman Sachs analyst who had co-founded Harmonic. She and Andreessen dated briefly, then became good friends.

Andreessen is now CTO at Ning, where Bianchini is CEO. What's that old saying?
