I'm always a little confused why hacker news seems to love to hate facebook. Pretty weak posts like this appear and everyone in the comments gets to brag about how they don't have a facebook or facebook is on the way out etc.
Posts like yours always show up too. It's cyclic insanity on HN. Any Facebook thread devolves into: "I don't use Facebook." and "Why do people on HN hate Facebook?"
Any PHP post devolves into: "I hate PHP." and "Why do HNers hate PHP?"
Any Google post devolves into "I hate Google." and "Why do HNers hate Google?"
1st day/time X is (+over the top adjectives) good / bad
2nd day/time X is actually bad / good
3rd day/time Why do people argue about whether is actually bad / good
4th date/time meta post about meta post
It is a social version of AOL; a walled, sanitized, child-proof, alternative internet kept clean and safe by its overseers. I can not think of anything a hacker would hate more outside of App stores on phones and the Great Firewall.
