I find nested quotes annoying especially when someone uses the function to add some silly one-line quip at the end of a pageful of the things.
Sadly though, it’s what happens, particularly when a thread had branched off in several directions. It ends up as one big fat muddle, a result of the refusal by Justine Roberts to spend any money on improving the site. All investment goes into Mumsnet.
Instead of the linear presentation, it would be easy to branch-thread the conversations so people could reply to a specific post without having to copy-paste relevant paragraphs, pages after others have been talking about something else entirely.
I know exactly what you mean Fallingstar. It tends to happen more frequently towards the end of a dying thread when nobody is reading or listening anymore, even if they ever were very much. It's very, very noticeable that many people don't bother to read what has gone before. One can try to bring a derailed thread back on track but it rarely works.
It’s a moribund site which I can see being closed:
a. because it’s massively loss making and
b. for the same reason Saga was closed.
