I don't get the words you are using. You have a scale with "frivolity of motive" on one end and "regard for truth" on the other -- but the two aren't really antonyms. Plenty of frivolous posts are true, and plenty of false posts (meaning -- posts that contain incorect information) are serious. Plus, you can't know motives. You imply a correspondence between style and substance that I don't see. People who act like jerks are often right.

But mainly, I don't think there can be any consensus about whether a given post fits your categories or not. It's very, very common that a strongly worded post will seem to some like a stand for truth and to others like snark. Attempts to make us better will seem to many as dragging us down.

I'm boring even myself. If I were to evaluate your top post, I would say it is one of the few lately that I've really enjoyed. I also think it's mostly wrong. My conclusion: truth does not equal beauty.
