Ok I’ve moved the thread that started this discussion to a publicly viewable section: https://elixirforum.com/t/can-you-increase-post-edit-time-limit/6080
With regards to real world problems we have several categories where the first post needs to be kept up-to-date, this includes:
Developer Profiles (example thread: Tom - Elixir developer - Dev Profiles - Elixir Forum)
Libraries (example thread: https://elixirforum.com/t/meeseeks-a-library-for-extracting-data-from-html-now-with-xpath-selectors/4315/4)
We also have sections for user’s Projects where I would also switch on extended editing for the first post, as well as a Learning Resources category which includes sub-sections that also act as an information resource that may need to be kept updated (we have a dedicated thread for each book, course, etc)
I don’t think it’s just this forum that would benefit from it, on a dog forum for example, we could have threads that act as a profile for user’s dogs, on a car forum, a thread for user’s cars etc. More generally, it could be useful for guides, how-to’s etc which need to be kept updated.
Traditionally, threads like these on forums become ‘stale’ - it would be great if we can avoid that with Discourse
