>a comment requirement would likely just encourage a low quality comment to receive more low quality responses >Imagine the opposite, if everyone who upvoted your comment had to reply "I agree" or something similarly useless.) I suppose it could be done Slashdot style where [AFAIK. I've not been on there for years] you don't have to write a reason for an up- or downvote. You just select from a series of icons representing; "insightful", "funny"... etc. A system like that wouldn't add much overhead to voting on a submission, but would give an indication as to why the voting had gone that way.
