This is what has killed Twitter. Both social justice Twitter and right-wing Twitter revolve around competing for status-points, and backslapping (the latest trend is linking to other people's egotistical tweetstorms along with a comment like 'This' or 'Thread'.

Very little challenge of ideas takes place - either from within communities or from outside. The whole thing has become a Wittgensteinian language game where people compete to praise or denounce the latest political trend in the most caustic or verbose way. It's tiresome and offputting to people unwilling to subjugate their entire online persona to their identity.
