The general audience of Facebook has very little overlap with HN commenters.

Average HN commenter is bright enough to close their account year ago?

Correct. But the general FB audience cares much less (if at all) about their privacy than the general HN audience.

If you were to estimate FB's health as a company based on HN comments only, it should have been dead and buried long ago.
