Your Internet Writer seems remarkably fine-grained. Tell me, have you ever encountered a soul who did every one of those things?

Yes, people do all these things. As you point out, and I'll agree with you, sometimes we do some of them ourselves.
We're all human, after all.
But few of these behaviours are the result of reasoned analysis. Why would anybody follow thousands of people with the intention of reading everything they write?
We live and learn, and we all take different paths.
