I know that when you have 8000 of it karma is utterly irrelevant. But in the interests of consistency it would be worth following the practice of having another comment which can be voted down for balance. People don't always actually downvote the karma sink but they like having the option to. Without a mechanism to distinguish approval for the principle of having a survey from the supplying of survey data itself the information provided will not even have a chance to approximate being accurate. The people here are the kind who frequent the spin off site of "OvercomingBias".
