Certainly, Rosenberg has been crucial to Google’s success, so his exit has come as a shock to pretty much everyone to whom I’ve spoken. That said, its timing seems quite convenient, particularly in relationship to what looks very much like a significant reorg that is currently underway at Google, said sources familiar with the situation. Note first that Rosenberg’s replacement wasn’t immediately named and it’s not clear whether Page even feels one is needed. Maybe Rosenburg helped Google do great things. Maybe I'm about to over-simplify. But weren't the things that made Google a true powerhouse created long before guys like this were hired -- back when the company was more engineer-driven? It seems to me that Larry Page's frustration has been growing as he watched MBAs take credit for the success the engineers had created years before. If that's the case then I wish him success in changing the company's structure.
