The trouble with echo-chamber platforms is they preach to the choir by reinforcing biases, beliefs and wedge issues, further dividing and conquering society into various polarized, separate subcultures. There ought to be a microblog platform that supports written debate of every belief, such that arguments can be settled online rather than spill over into the real world. The powers that be love it when the "little people" argue over abortion, climate change, separation of church and state, criminal justice, the War on Drugs, et cetera ad infinitum. Without civilized debate, a civilized society is impossible.
