The comment is from hacker news thread about Bitcoin hitting $100. It would be cool to have him also expand more on bitcoin itself which he seems to regard as destructive but not necessarily doomed to fail? Here he entertains the idea about combining NGDP level targeting (which I don't understand) with the best parts of Bitcoin. This all sounds very interesting.
I downloaded a Bitcoin client a couple weeks and was going to buy a few bitcoins, but the inconvenience of having to get a Mt Gox account or something made me keep on putting that off. Whoops. Hopefully this'll teach me to be less of a procrastinator.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
