From what I gather from his comments, Jimmy Wales appears to be an ungrateful asshole.
Give Jimmy some time and the respect he deserves - he has already given so much to the online community.
He is new to all this and needs guidance - when many of us here first got into Bitcoin it took a while to wrap our heads around the concepts involved. Give him a chance, it's been said that Bitcoin is the spiritual cousin to Wikipedia so it shouldn't take a smart man like Jimmy long to fully comprehend what all the fuss is about.
