Well, that didn't take long. Less than two weeks after Yahoo announced that chief technology officer and chief product officer Ari Balogh would be leaving the company, a semi-replacement's been named: Blake Irving, a former Microsoft exec. This development doesn't come as a big surprise; when news of Balogh's decision to quit first broke, the rumor mill already had Irving assuming Balogh's CPO role. Still, this hire looks to represent a significant win for Yahoo.
