Twitter has hired Alexander Macgillivray, Google's associate general counsel for Product and IP, as their new General Counsel, we've confirmed. Macgillivray is still an employee of Google, and his start date at Twitter has not yet been determined. We've been sitting on the story all day and were trying to talk with Macgillivray because our understanding is that he may not have told Google that he was going to Twitter and we didn't want to be the one's to break the news.
