Last weekend, around 60 entrepreneurs under age 35 flew to Cancun for a retreat informally dubbed Summit Series. CNET reporter Caroline McCarthy was one of the press attendees who agreed not to name names. Nice try. The list of attendees identified below includes Dave Morin from Facebook, Joe Green who roomed with Mark Zuckerberg in college, and Sam Lessin who just got back from lip-dubbing Journey at Camp Cyprus. Tony Hsieh just laid off 8 percent of his Zappos staff. Ex-Googler Chris Sacca may or may not be rich, but I'm jealous of him anyway.
