Om Malik's smart move

Blogger Om Malik could never have predicted he'd have a heart attack at the age of 41. But he did foresee one thing clearly: He would never build a business on a single blog so closely identified with one author. His spinoff blogs ��� Web Worker Daily, NewTeeVee, Earth2Tech, and FoundRead ��� have not matched GigaOm's success; of the four, only NewTeeVee, in my opinion, shows promise of being a breakout hit like the original. But unlike Michael Arrington, who built TechCrunch solely on his startup cult of personality, Malik has sought to diversify his media startup in a way that it can survive him. Until December 28, this was merely wise in theory.
