A word of advice: Perhaps anyone posting a comment here with the intention of voicing a contrarian opinion and getting upvotes for disagreement should indicate the fact explicitly in their comment. Otherwise I predict that the upvote/downvote signal will be severely corrupted by people voting "normally". (Especially if these comments produce discussion -- if A posts something you strongly disagree with and B posts a very good and clearly-explained reason for disagreeing, what are you supposed to do? I suggest the right thing here is to upvote both A and B, but it's liable to be easy to get confused...)

[EDITED to add: 1. For the avoidance of doubt, of course the above is not intended to be a controversial opinion and if you vote on it you should do so according to the normal conventions, not the special ones governing this discussion. 2. It is possible to edit your own comments; if you read the above and think it's sensible, but have already posted a contrarian opinion here, you can fix it.]
