"few people with _serious_ technical chops want to play on Facebook's side of the garden wall" I fear you suffer from some form of bias. Or maybe I do; however, I know some folks there who, in the devops or data engineering world, get it. I mean you had Taner (who also lent his hand to building battle.net's infrastructure), Keith Adams, JPC, David Reiss, John Allen, eric huang, sam rash, etc. Their largest hadoop cluster has _several_ hundred PB of data. You don't manage / run things on that without having some chops. Period. If you read the under the hood series, you might be able to see a different viewpoint.
