Officially, the New York Times Company isn't commenting on tech executive Jason Calacanis' claim that it is shopping reference site About.com in an effort to shore up its financial position and perhaps go private. But two anonymous sources poured cold water on his statements, according to Peter Kafka of All Things Digital, denying that the profitable property is on the block. Perhaps a rogue banker is trying to drum up interest in a (hypothetical) deal before taking it to the Times, hoping to score some business. Or maybe Calacanis just got his wires crossed. But lack of any dealmaking will hardly tamp down speculation over how the Times Company will pay down its junk-rated debt. If anything, it makes the situation an even more tricky puzzle.
