That is kind of funny, because Twitter can totally be that, if you want it. You have to be liberal in your usage of the block button, but the advantage is that you have so many genuinely interesting people to follow and learn from. I wouldn't have 1 in 1000 of those on Masterdon, and with their doubling of tweet size, I don't see the problem with arguments.

Before anybody goes about the ecochamber: I ban obnoxious people, self-promoters, bad arguers, I don't ban for sincerely held, well argued politics. I follow a former cam girl, a couple in the rational altruistic movements and a Catholic, pro-life convert.
