Last week, we reported that AOL was in the market to buy another ad network. Then, over the weekend, reports came that the Time Warner unit will pay $300 million for Israeli ad network Quigo. Mazel tovs all around, of course. But the big loser in the deal? Yahoo, natch.

A tipster writes in to tell us that Yahoo tried to buy Quigo "3 or 4 times" but that the deal never happened. Why? Our tipster tells us Quigo CEO Mike Yavo and Yahoo exec Chris Bolte couldn't find a way to fit their egos in a room together. Which strikes us as implausible. Other than an offer to jump ship, what does a Yahoo executive have going on to feed his ego?
