2. Sometimes ... tootstorms just happen.
3. It is ... remarkably like posting a public Zettelkasten. In particular, there are often responses to specific items on a thread and those themselves can prove revealing.
A huge issue with traditional "single entity" documents (books, essays, even longish HN comments as I'm wont to produce...) is that responses tend to be either to the thing-as-a-whole or some irrelevant point. One of the hardest things to get as an author is specific feedback to a given passage of writing, and for all its many, many faults, the tootstream format cracks open that shell.
That feedback may highlight well-written bits, poorly-written ones (where readers repeatedly misinterpret authors' intent), salient or poorly-supported facts and logic, etc.
My usual platform for this is Mastodon, and I've posted a number of longer tootstorms (using the Mastodon nomenclature rather than "tweets"), searchable via hashtag from my present and previous instance homes at

I thought there were a few here as well though they're not appearing:
