But the reason people aren't making forums, is it is not as easy for community owner to make forums (need to get cloud storage, then configure something like discourse forum, get a domain name etc.)
Same for the end user who wants to be part of multiple communities, has to remember the URLs of multiple communities, has to have multiple logins and passwords and needs to create an account in each of them.
If someone combines discord + discourse (basically an app, that has all your forums on the side bar with just one login, and people can create a new forum for anything, similar to how you can create a discord server) then I think we might end up going back to forums with more meaningful discussions and all information related to some issue in one place.
