A tipster tells us Yahoo senior directors George John and Subhhash Bhatia didn't finish the day employed yesterday. John, our tipster writes, wasn't a particularly harmful presence. Bhatia, however, ran his "division completely into the ground, forcing managers and engineers to flee to other parts of Yahoo — anywhere but under him. It's a pity that it took layoffs to let him go." Psst, Subhash. If you have a guess as to who the tipster is, this means you shouldn't ask him for a reference.
