Having cleared his name of obstruction-of-justice charges, former Credit Suisse tech investment banker Frank Quattrone is launching his own boutique firm, Qatalyst Partners. Several big Valley names volunteered quotes for the press release. It's not surprising that Google CEO Eric Schmidt, who's made his own moral missteps, would be forgiving of Quattrone. But Gideon Yu, Facebook's CFO, makes a more curious appearance. He gave a statement applauding Quattrone's partner Jonathan Turner, not Quattrone himself. But still, it amounts to an endorsement. Does Yu really think Quattrone did nothing wrong? Or, as a minister's son, is he just expressing the highest form of the Valley's belief in the power of redemption?
