> sites where real discourse is still possible without it being filled with memes, running jokes, “witty” one-liners [etc]
There are subreddits within Reddit such as https://www.reddit.com/r/neutralnews/ that have strict rules around sourcing, etc. However, I think that’s not what most users want, and may not be quite what you’re looking for either, apologies.
Eh - it IS what most users want.
In the same way people want to be fit.
There are 3 horsemen of Internet forums, one of them is topics with a low barrier to entry.
At that point anyone can speak up, and their opinion takes up as much screen real estate and reading time (often less reading time) than a truly informed take.
By putting effort barriers in place, it forces a fitness test that most users (and bots) fail.
Another subreddit which has strong rules is r/badeconomics. I didn’t know about neutralnews, so thank you for giving me another example to add to the list.
