Here's an amusing comment policy.
While I think it's perfectly reasonable to reject comments from people who are raving, a couple of points about this seem designed to stifle any dissent. Not including links says that posters are not allowed to provide references to support their arguments, even though that's a cornerstone of any good analysis of a topic. And it's difficult to make a serious argument in one hundred words, not to mention that such a limit prizes quantity over quality.
Do you want to people to read reasoned argument against your posts? Or do you want only comments saying, "Oh, you're so right"?
I managed to keep the last two paragraphs to one hundred words, and submitted them as a comment. Do you think they'll post it? I think it conforms to the letter of the rules, but not the spirit, so my bet is not.
