> Text forums have effectively been solved ever since NNTP was invented.

Yes, and you should use that. I even have NNTP service with newsgroups for my own projects but they are not used much, so far. I would hope that other people can easily set up their own forum (like you say is possible with Reddit), possibly with any number of remote services which have NNTP access as well as HTTP perhaps, and if you set up an account then you can set it up and it can also be federated. ActivityPub and other HTML-based forums are not very good I think, and NNTP is much better in my opinion (although bridging can be implemented if it is desirable, some things might not work very well in all protocols e.g. ActivityPub only works with Unicode). (There is one change to the protocol which I think should be useful, which is to allow 63-bit article numbers instead of 31-bit article numbers. My own server and client software implements this feature.)
