You can also go backwards, The problem with social media is that anyone can comment on it. and that's not a desirable trait for complex discussions. I can't tell how many times I've seen a news article and the top post in a forum like here or reddit be some expert explaining the article and indicate the failures of it. This is solvable, a social media for experts, every single link given a rating on its truthfulness. by actual non-anonymous experts. or hell, you can scrape for the link on twitter, have a database of professionals who have commented on twitter on the article and indicate what they said about it. Anyway, I'm just spitballing now so I'll stop.
