How leaky is Facebook? So leaky that new hires sometimes out themselves right on the company's own website, as tech expert Jonathan Heiliger has done. Heiliger, you see, revealed his new employer by joining the company's private group for Facebook employees, a move that's visible on the site. Heiliger, who, back in the '90s, used to be a 20something rock-star Internet executive like new boss Mark Zuckerberg, will be the company's vice president of technical operations, charged with, oh, say, making sure the site doesn't crash, spew private data, or leak code. By my count, that makes Heiliger the fourth vice president with "operations" in his title. But I think Heiliger, a veteran of bubble-era companies like GlobalCenter and LoudCloud, will spend more time regaling Zuck with war stories about what it was like to run a ridiculously overvalued Internet company. And he'll thereby get to relive his fading youth. What a job!
