Also, I completely fail to understand what Douglas Rushkoff is suggesting here: open source currency.

Do I need to read his books or something for this concept to make sense? He seems to be suggesting that we need money that isn’t controlled by the government, and that a model of money that is based on abundance rather than scarcity will enable an economy of collaboration rather than competition. What? Can someone point me to articles that will give me more specifics? (Naturally I will also be trying to Google this myself.) This article is just too vague for me to make sense of it.
