I think its more a question of how you view nodes in context. (...) This means that the node you post is actually a subnode of a preexisting structure.

This is a good point that I had not considered yet. To be honest, I added the readmore tags mostly to avoid the need for consideration. I had no idea that it would be subject of consideration three times after that. I don't visit the front page, and I visit main section pages only when starting a new thread. So I didn't really think about any pre-existing structure.

The only solution for this, however, is to not use structured heading tags at all. And that sucks, because the alternative is font tags with size attributes. One can argue that the number in h1..h6 is for font size and not just for structure, but if this is the case, then CSS should be used to make them smaller so they can still all be used. I add that I like to be able to paste things from my web site or that are generated by pod2html.

Dynamic changing heading tags is not possible, because the number of levels is limited. Font size sucks, because replies are smaller than the rest, and users should always be able to override this. And screen readers won't recognize structure if the document isn't html-ly structured.

Is there any solution to this problem?
