I recently received my first downvote and am still reeling from that stinging feeling. It seems silly to care, but, for some reason, I do. What is more frustrating than getting a downvote 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 downvote 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?
