Former AOL Time Warner COO Robert Pittman and his partner Andrew Russell have joined the investor roster of GeekChicDaily, the fanboy-geared website founded last fall by web entrepreneur Peter Levin, Wizard Entertainment’s Gareb Shamus and Mandalay Entertainment Group CEO Peter Guber. Pittman’s investment is low six-figures. Pittman was an early investor in Daily Candy, hatched by Pete Sheinbaum and sold last year to Comcast for $125 million. Sheinbaum also joined the GeekChicDaily board.
