good to see Alex come around... i know he was skeptical a year ago.
Who wouldn't have been skeptical last year with all the silk road disasters as well as mtgox faking trades (not that anyone knew it at the time)
Good news tho
I think there were a lot of people who believed in bitcoin a year ago. I would argue that the Silk Road seizure got a lot of people to start using bitcoin (for less then legal purposes) and Silk Road in general likely was able to get bitcoin on his feet.
I highly doubt that MtGox was faking trades, although them loosing all those coins did likely hurt bitcoin long term.
I wouldn't say that this Alex guy is going to particularly help bitcoin overall, he doesn't seem like exactly a roll model, although I doubt he would hurt bitcoin either.
