Every place you let “anybody” post, there’s going to be mis- and even dis-information. If you think otherwise, you’re not thinking about how hard it is to double check every single post. How long do you take to write a response to something you see here. How long would it take if you didn’t already have an opinion or/and expertise? Sure, AIs can maybe do it better, but maybe not so much. Oh, I know: Your post cannot be seen until after it’s checked. No instant feedback. Think you’d stay on that forum?
Bottom line: Facebook is embracing the noise and junk, and the others are attempting to keep it clean… and failing. I’m not saying the FB way is better, but it is at least being overt about what’s happening.
