I'm curious what attracted John's interest in bitcoin. It's interesting to see so many financial experts are watching it. I see the main difference from previous attempts at digital cash is that there is no way to stop people from using it and its at least as untraceable (and untaxable) as regular cash.
What attracted John's attention is a crowd of people talking about finances that he could exploit to drive traffic to his own moribund site. Combine that with the likelihood of slow business and John is hoping that he can drum up some clients if he talks pseudo-intelligently about finances. This joker is all over the map though. In here he decries the bubble/ponzi/pump and dump nature of BitCoin while over here:
http://forum.bitcoin.org/index.php?topic=21384.0 he gushes over the stability of the currency at $15.
He's either a) bipolar b) several people who aren't comparing notes or c) playing every side of the argument in hopes to attract a dupe to his services.
Whatever one of those things he is, he is primarily a troll.
