> I think you're under the impression that facebook's job is to be good at showing you what you want and being useful. I'm pretty sure they think their job is to balance being just useful enough that you don't quit while maximizing revenue from you, which might entail being pretty crappy to use overall.

This is just a minor quibble to lambda_lover's point, which still stands. Facebook may understand it's job is to shove as many ads in its users' faces as they will tolerate, but that's not why users use its app. It's users view its job as being useful to them, and being bad at that makes makes FB vulnerable to competitors or even just general dissatisfaction.
