Twitter is not a town square. It's just a place where journalists, activists, trolls, and bots gather to communicate in an unhealthy and miserable fashion.

Those who want to communicate about things that are productive and enjoyable are not going to get it on Facebook/Instagram/Twitter... it's more niched. The only reason to create accounts on those platforms is to get people to come to the niched platforms and then eventually come back for more without needing Twitter as a referral source.
