Six Apart consummates Apperceptive acquisition, fecund pair already preggers with yet another ad networkAs a part of a new "blogging services" strategy, blog software firm Six Apart has acquired social media applications builder Apperceptive and launched a new ad network. SAI questions whether the world needs another ad network. It doesn't. But we also wonder about Six Apart's timing. Why not launch the ad network during Ad:tech a week earlier? The Moscone Center crowd might have liked to lay some bets on some SXSW-style kickball action organized by publicly snarky, privately earnest Six Apart marketing guru Anil Dash. All we got were booth babes in fishnets.
