Wow. I've followed the progress of bitcoins for several years, and while I'm not really surprised to see this development, it still falls into the very cool category. I wish I had been able to figure out a way to work my way into the bitcoin explosion in the beginning when I first learned of them. They had just started, were being "minted" in large quantities and there were many ways to earn or acquire them. I knew that there was a lot of money to be made back then, and I did see this coming. Another failed dream of mine. Still, it's very cool.
