Have any of you ever heard of Bitcoin?

“Bitcoin” http://bitcoin.org/en/ is a brand new currency system for use over the internet. It is an actual currency, like dollars, yen, pounds, rupees, or even rubles. It has a value on the currency exchange. I was just wondering what people think of it. Do you think it could be a success, or do you think it is doomed to fail. Explanations are appreciated (hint hint).
