With the Community 2.0 event coming up in May, we're going to take the few months before that to introduce you to our keynote speakers for this year's event. Twice a month, we'll share with you one of our featured key note speakers. Community 2.0 is May 11-13 in San Fransisco, California at The Palace Hotel. This week, we're featuring keynote speaker David O. Sachs, founder and CEO of Geni Inc and Yammer, and former COO of Paypal.

Sachs was the founder of Paypal, and created a company worth $1.3 billion when sold to eBay in 2002. He then moved to Los Angeles and produced the movie Thank You for Smoking.

You can see David present his keynote speech "How Micro Sharing Tools Make Enterprise Communication More Efficient" on Tuesday, May 12 at Community 2.0.

Listen to David O Sachs' podcast with Venture Voices here.
