Yes. If you look at my recent comment history, you'll see that, by far, the most effective strategy I've found for getting comments with lots of upvotes is to find a factual error in somebody else's comment and correct it in a clear and unambiguous fashion; and within that constraint, the shorter the better. You'll see that I got a comment consisting entirely of "[citation needed]" voted up to 7.

Long comments have essentially no chance of being voted up significantly. Other things that have very little chance: speculations about the implications of something, wild and surprising analogies, speculation on others' motives, advocacy of norms. This is really unfortunate, because those are the comments I most value reading. I really get no value, beyond a little humor, from reading that gorillas aren't monkeys, since I already know that.

"Really, people? You modded me up to 17 for making a nitpick about simian taxonomy?"

If it makes you feel better, I gave you a point just for that comment...

Ook, ook.

You forget your place, sir.
