When I reply to the last comment in a section, a new thread is started instead of adding a sub-comment. Maybe there is a way to do it, but I don't know how.
Topic on Talk:Structured Discussions
Sorry for the late reply.
Do you have this when logged-out? On which wiki do you experiment that?
What steps do you make?
I experience this in any wiki, for instance now, instead of created a nested comment when replying to your comment, it creates a comment on the same level.
Your reply is not a new thread. It is a reply. Like it is a reply on a lot of other websites.
Replies are not nested like they are on wiki when using wikitext. It helps readability by having all replies at the same level. Some people like that system, some others don't.
A consultation around talk pages will happen in a few weeks. It would be the best place to share what you like or dislike concerning the different discussion systems that exist or would exist.
The way I see it is different. Inside each thread there can be many sub-threads, when I reply to a the last sub-thread, the reply should be nested, as it happens when I reply to a sub-thread that is not the last one. If I want to start a different sub-thread, that should be optional, not the default. Otherwise the meaning is lost when other people reply to comments that happened before the last one, and then there is no way of knowing to who the last person was replying to.
Looking forward to the consultation!
