Incidentally, this reminds me -- later Summer this year, I had the chance to meet a lot Linux kernel developers. At some point a handful were speaking casually about Facebook -- and guess what, each and every one of them were 20 times more paranoid about Facebook and its intent than I am (and I'm pretty skeptical of everything FB does). I'm honestly very confused. I don't want to make the jump and say "astroturfing" -- but I don't know, maybe we have some Facebook developers here who probably work on some engineering tasks and never are exposed to the questionable side of things and genuinely think FB is up to only good. In real world, every true hacker that I personally know greatly distrusts Facebook and all that Facebook touches.
edit: ok, I think I may have said that a little too soon. Posts doubting Poitras are now more toward the bottom than the top, and my two posts are no longer negatively scored.
