Just two weeks before San Francisco's 2011 mayoral election, billionaire angel investor Ron Conway pushed out a viral campaign ad for Mayor Ed Lee that featured cameos from local sports stars and Silicon Valley tech celebs. Now, 13 months before Lee's next election, Conway's techie advocacy group has released another ad including all the hallmarks from the original "2 Legit 2 Quit" video.

In case you missed the all the glowing profiles of Salesforce CEO Marc Benioff this week, the billionaire's philanthropic efforts have crowned him "the most influential man in San Francisco." And he's wielding that influence to "shame" his rich friends into giving back.

Ron Conway, the pioneering angel investor behind the "spray and pray" technique, has put his $9.5 million "Louis XV style" abode up for sale, reports Business Insider. According to Trulia, the price for this full floor apartment in one of "San Francisco's most desirable co-op buildings" has recently dropped half a million.
