Techies gather for a lunch to save the world
The 43rd floor of the Spear Tower in downtown San Francisco is empty. Possibly because of the slumping economy, there's just a big, open office space with unfinished white walls overlooking a million-dollar view. It was an appropriate setting for Lunch for Good, an event on Wednesday that brought together nearly 100 people deep in the Bay Area's social-networking industry to talk about a futuristic question: how online social networks can help humans find common ground.
