... if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin... Some of them are sure to attract users with promises like "Why use bitcoin, where you can only generate 50 bitcoins every few months? Use shitcoin instead, and you'll get 51 shitcoins every 2 minutes".

Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies" like flooz and beenz, but lots of people will get burned along the way.
