Ah, geek celebrity. While publicly Google is viewed as a meritocracy, working there you quickly realize that it's very much a hierarchy of intimidation and arrogance. You may have great ideas, but if you really want to be successful you need one of the Google engineering celebrities to back your play. These "chosen ones" aren't in their position because they necessarily have the best ideas; in fact, many of the good ideas at Google are never explored because folks with social influence express doubt. Marissa Mayer isn't the only one in engineering, she's just the most famous.<p>As the company increases in size, the meritocracy of ideas fades and being a good politician becomes more important. While it's not the primary reason I left after five years, it was certainly a consideration.
