Joe Collector: Derogatory term for a person who purchases mass quantities of wax, but doesn't actually collect the cards. Term made famous by cardblogger Adam Gellman.
According to Gellman, Joe Collectors "Are those certain collectors that post all their maildays on message boards, use “Mojo” in really annoying ways, live for making a profit on cards, and have no problem fighting you tooth and nail on any sensible point about the hobby. They are generally so UNINFORMED that they fight to remain in their ignorance. They price all their cards using Beckett instead of current market value, and they thrive on the glory that they supposedly get for everything. They use an abundance of exclamation points in anything they post and they love to make sure people know that they have a very high opinion of themselves."
