> people want to go where their "friends" are There's another flip-side to this which is particularly important towards the more extreme end of the right wing - some people want to go where their enemies are. That Twitter allows you to jump right into the middle of a discussion and directly engage with or antagonise those who you dislike is a big draw. For those into reactionary politics, being siloed away in a little safe zone with people who agree with them isn't particularly gratifying. edit: I agree with your comment btw, I just wanted to add a little something to it :D
