This is amazing, one of the best defences of bitcoin that I've seen yet I think. Found it recently on twitter and just wanted to share. It's a bit of a read, but should be well worth it for many around here : http://bitcoinmagazine.com/bitcoin-is-not-antisocial-a-rebuttal-to-paul-krugman/

(surely it's already been posted on this site too, but I'm still confined to the newbie holding cells for a bit yet so haven't looked elsewhere much.)
