2 BTC says BitcoinEXpress is really just some big-talking nobody living in his mom's basement.
Nah, I'm sure he's making semi-big bucks as a customer service rep for Dwolla. Hey, if he almost manages to use a forum, like putting his reply in the quote body, he might even be a manager.
My guess is that BitcoingEXpress/OrangeSun is an escapee from the Republic of Sockistan. Happily forum.bitcoing.org has the good sense to offer refugee status for general amusement. It must be dawning on him by now that this isn't the typical day-trader/silver-bug forum. Maybe not though...he does not seem all that quick on the uptake.
Another hypothesis is that he is actually trying to bring Dwolla down and elevate Tradehill. Seems like every time he shows up he gets his balls pounded flat and Dwolla gets another shiner.
