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!
