I like the idea of Bitcoin, with one exception... that the resources could be used for grater good, instead of wasting them.
Anyway, sorry for the rant, I've done seti, folding@home and a few more, but bitcoin? bitcoin is not about philanthropic egos or greater goods of scales we aren't really equipped to grasp. It's all about the fairness and privacy of community markets, something all of us below the age of, what, 120 don't really understand and have been taught to loath.
More like under age 25. Market anarchists are a very young demography. We only got a few old market anarchists in their advanced age like Eric Raymond.
