7 things every Facebook user needs to know:
Eric Barker stashed this in Facebook!
Guilty as charged:
"Dunbar's number says we can only sustain 100-230 friends. It holds up online too; despite how many "friends" you have you're probably only active with about 100-200 of them consistently. Facebook promotes mainly weak, low-commitment friendships anyway. And the main reason for un-friending is because somebody posts too much uninteresting crap."
Facebook is great for helping me maintain friendships that might otherwise wither but if i really want someone to be one of my "Dunbar 150" I think it requires an effort above and beyond the bright blue confines of Facebook.
