This is true and I bring this up as well BUT consider this: probably less than 23% of US citizens make 90% of the important decisions for this country (the power law still holds) and if all of those people are on Twitter then OP's point still stands. I deleted Twitter about 3 months ago and it's been great. I can just focus on life and talking to my friends still on the platform I realize just how much of a bubble it really is and how most of the issues everyone gets hysterical about is just irrelevant in my life. That being said it seems to hold an insane amount of influence in the minds of journalists, business leaders, and politicians and thus it is an incredibly powerful platform.
