Frank Addante, CEO of the Rubicon Project, a Los Angeles-based online-advertising startup, mocks himself so you don't have to. Another pointless ad network? Clueless execs? Gullible venture capitalists? His latest video, made to introduce himself and his company to attendees at The Lobby, a Hawaiian tech-dealmaker junket organized by venture capitalist David Hornik, embraces all the possible criticisms one might make of Addante. Except for this one: He has enough spare time on his hands to make videos and go on a thinly disguised Big Island vacation. That's the real joke, in case you weren't getting it.
