Agreed, but I would point out that if I were an FB employee and I disagreed with the memo, I certainly wouldn't be saying "yeah, we suck" on the highly-traceable internal discussion board! I'd say that stuff face-to-face with people I trusted at the water cooler or something.

There's a strong selection bias at work here in these posts and I think it's a serious statistical error to assume this represents the median view of Facebook employees.
