I wonder if the signal people actually want is "low information density" rather than "AI-generated."

A lot of the frustration seems to come from content that takes 2,000 words to say something that could have been said in 200, regardless of whether a human or a model wrote it.

If a post is original, useful, and teaches me something, I don't care much how it was produced. What I notice is when a lot of words are used to communicate very little.

Yes, but low information quality is even worse than low information density. If I happen to know the subject well, and the article contains glaring errors, obvious omissions, or miserable fudges - I'd like a quick way to tag it as dubious.
