I don't get this Facebook rage every year. Last year it was about the open social graph API and the third-party like buttons. Everyone was mad at Facebook. Calls for boycotts, mainstream press picking it up, Diaspora, etc.
Then it dies down and everybody seems happy about Facebook.
Until a year later, HN is full of hate-posts again. So, if history is to repeat itself, I'd say that the hate will have died down by June and I'll get my hate-blogpost ready for next year, having missed this years Facebook-hating-season
