Like a summer-fair wrestler extricating himself from a sweaty sumo fatsuit, Yahoo cofounder Jerry Yang is finding himself in a sticky situation. Yahoo's second-quarter earnings have come out. Without much of a track record as a manager, and an exceedingly short tenure as CEO, it's hard for Yang to take credit for any successes. But having hastily replaced former CEO Terry Semel, he's a handy target for shareholders looking for someone to blame. I listened in to today's earnings conference call and blogged live, after the jump, as Yang gave his first accounting of himself as CEO. Also on the call: President Sue Decker and CFO Blake Jorgensen.
