There seems to be a steady stream of these from ex-Googlers, which is frankly what I'd expect from a company of that size. What I'd be interested to know is what percentage of SWE's are leaving each year, and of course how do the people that are left feel about the company. The ones that I've heard from have a range of opinions from It's Ok to It's Great, but those are of course anecdotes.

Also, "behaviors that lead to success" are not necessarily the same as "behaviors of the successful". Lots of folks have effectively won the lottery.
