The forums of old times still exist in some corners of the internet. They used to be big and there was one for pretty much every topic.
But most died over the years or got replaced by services like Facebook groups, Reddit or Discord.
Are you still using proper forums, which ones and why haven’t you made the switch to other forms of communication?
This one. I don’t like the other things you mention. I did join a sub reddit on the topic years ago, but it was awful. Full of people who didn’t know anything of the subject, but were very willing to downvote.
