CEO, AOLTim Armstrong shocked the online-advertising world when he announced in March that he was leaving Google to helm the much-maligned AOL.

He's also running a newly public company, as of Dec. 10. Will the strategy work? Too early to tell. But wouldn't it be rich if AOL, of the disastrous Time Inc. marriage, redefined consumer media for a digital age?
