I don't disagree with all your points, just some, 2 & 3 specifically. Both are related to attention, to some extent also the "bonus" remark. I don't think people need to rely on hooks or other unrelated elements in their content for people to be interested on a platform where the dynamics of advertising is absent. Here quality of the content is what matters most. So that should dictate length, detail, or style (which is also why I really liked your "ultra bonus" remark).

Maybe I should have led with that, and been more precise with my words in my original comment.
