I don't remember when exactly I heard first about Bitcoin, when it was mentioned I never really got informed about it and just assumed it was some some virtual currency similar to gold in World of Warcraft.

When I REALLY found out about Bitcoin was about a month ago when alot of the banks in The Netherlands were having problems with they online payment systems / being DDOS-ed and I saw some tweets along the lines of "at least my Bitcoins are safe" or "time to switch to Bitcoin", then I actually took the time to research it and got fascinated by it.
