Wasn't it just yesterday that Google was the coolest company on the planet? The New York Times says the online giant is now seen by techies as a lumbering behemoth, and key employees are starting to leave for more nimble companies.

In your experience, do large companies offer the same shot at success, or do workers usually have to break away to seek the greater rewards?
