The worst is that Quora paid its own users to spam the service with questions they didn't actually need answers to.
You think you're helping a real human, with a real human need, and then you see he's asked not only what museums you recommend in your hometown, but also what museums you recommend in 400 other small towns from all over the world, and what restaurants you recommend for 400 other random small towns, and then what local radio channels you recommend for 400 more etc.
I find that most of social media went south around the time of Trump's election and the heavy partisan moderation that followed it.
Quora further seems to have been taken over by Chinese paid writers.
