Encouraging people to explain down-votes
I recently received my first down-vote and am still reeling from that stinging feeling. Seems silly to care but for some reason I do. What is more frustrating than getting a down vote is that whomever gave it didn't have to identify themselves, nor did they have to give a reason. Does this make sense to anyone? It doesn't to me. If the purpose of a down-vote is to let people know your answer wasn't helpful, then perhaps it should be required that, at the very least, you have to give a brief explanation for why you think it was unhelpful.
As for that stinging feeling, well I'll get over it I'm sure but now I will be much more reluctant to respond to a question in the future. Is that what this site is really about?
