I think conventional forum sites hold a much higher level of user experience & integrity than unified forums (like Reddit) or social media (Fediverse).
Maybe not "higher" but "different".
Having to access the domain, create a unique account, and fill out a "Captcha" box is something very few spammers/trolls would care about doing, whereas on Reddit you already have access to every other sub around.
I kind of miss the old forums I used to be active in (even though I was usually "the idiot" 😅).
functional.cafe is an instance for people interested in functional programming and languages.
