I think its a good idea about giving out points for the survey. Then more people would do the survey. But you could have the points once only if you complete the survey. I think its greedy to ask for a card or badge for a survey.
Although this is starting to diverge into somewhat of a constructive conversation a about getting points for the survey the thread make literally told us he was joking, and only made the post for fun. So don’t think he’s actually asking for a card or badge.
