Who is this joker? Why, it's venture capitalist David Hornik, the pocket-sized B-lister who has invited some of Silicon Valley's shallowest thinkers for a company-paid vacation. The three-day, mostly agenda-free funconference has opened tonight on Hawaii's Big Island, with attendees Twittering about drinking mai tais and dancing the hula. What, work?Why, that's for employees, not founders. The employees that Lobby-goers didn't lay off before boarding a jet to jaunt across the Pacific, that is. We hear some of this year's attendees, concerned with the appearance of attending such an ostentatious waste of time and money, tried to cancel. Hornik told them there would be no refunds. You know times are tough when a VC is being this tight about $3,000.
