Apparently Mr. Jarvis has not read the comments on the New York Times Amazon article or other venues like slashdot or Hacker News. There were lots of posters who wrote that the NYT article was largely accurate. Many posters described an environment with unusually high turnover, even for a technology company.
I find all of this disturbing since I am heavily committed to Amazon Web Services. I depend on AWS continuing to provide leading edge software and infrastructure. If they have high turnover, then this is going to be more difficult to deliver.
