While the idea of "downvote requires a posted reason" is no doubt the best idea, if it proves too radical a change from a technical or behavioral reason, at least radically raise the karma need to downvote. Say so that only the top K number of accounts by age or karma can do so where K is _not_ a percentage. Because honestly the number of down-voting-for-poorly-thought-out-postings is now mightily outweighed by down-voting-becuse-I-dont-agree. So much so that to be honest I now take downvotes as a badge of honor ironically.
