I wish we did, I think they went out of favour because most people prefer the “speed” of platforms like Reddit, where threads are active for a couple of hours and then something new comes up and a new conversation starts.

The problem is, there’s no accumulation of knowledge, it’s the same arguments and information getting repeated every time a new post is started on a similar subject.

You can’t tell someone “Discussion is already happening on this subject in this thread, so we’re deleting your post” when discussions don’t get bumped to the top and discussions don’t stay active once they’re not on people’s front page anymore.

The threaded replies don’t help either, it’s impossible to keep up with a post that gets a lot of attention since you can have hundreds if not thousands of branches spreading in all directions…

There’s a good reason why specialized discussion platforms all use forums instead a Reddit style system, they want to build a knowledge database and they do, plenty of active threads that are over a decade old on many forums all over the internet!
