I have to admit these Mt. Gox clowns are good. I mean really. They have a major flaw in their system that leads to bitcoins being hijacked everywhere then they use that to pitch a $29.95 product called the "yubikey" LOL'd ... probably costs $4.95 to ship and $1.00 to make making a $20 profit per key .... you can't make this shit up! welcome to the world of we fuck it up and make money! 
Hey, go research before you make your nonsense claims. I'll pay you 20 Bitcoins if you can tell me where to get those $1 YubiKeys.
YubiKeys aren't something 'made up' by Mt. Gox, they are used by many services that require 2 levels of authentication.
