No, I hadn't found that. Thanks. Those links answer my question.

I see your point.

Maybe it depends on how you use org-mode and how you imagine the meaning of the "*" items. I see some disagreement about this in the old threads that Max linked to. No need to rehash it deeply here again; I was just curious.

The way I'm using org-mode so far, I'm not exporting to other formats, and I can see a use for collapsible sections in the middle of a larger chunk of text. I can already kind of do it with a "-" list item, like this. (Or other things like code blocks, etc)

* Heading
Top Text

- Sub
  This can be hidden if I hit 'tab' key on "Sub".

If you view a "*" item as "book section", it's confusing. But if you view a "*" item as "collapsible thing", then it makes more sense.
