Why would anyone feel ashamed to not donate? And don't use reverse psychology, please. Donating to this guy to go to Paris is about the same as donating your money to the trashcan.
Im guessing that they are very appreciative of all that MD has done over the years and his reporting to let us know what he knows. Not to mention him poking at the Blizzcast officials to ask some devs a question. If I had any money I would gladly donate but being a student and having spare cash is always a problem. ( Maybe I should have people donate me money )
