One important point stuck somewhere in the middle is his observation that in the physical world, no public square, or public debate looks like what's on display on internet social networks. All of them have rules, civility is a thing, if you're crazy someone's likely going to throw you out, there's identity instead of anonymity and so on. Most people that I see behaving horribly on social media platforms do so under their own name, or at least an identity easily matched up to a real person, probably because they don’t feel like the repercussions affect them. So I don’t think the anonymity is that much of a cause or enabler for misbehavior in practice. I think the idea of being thrown out of a bar for misbehaving is an interesting analogy. On twitter you can be thrown out of someone’s personal timeline, or you can be thrown out of all of twitter. In the real world that would be like either you are refused entry to someone’s home or you get thrown out of a country, with nothing in between. It seems like there is room there for more variations in between. Maybe hashtags could have moderators that forbid abusive individuals from using them, or maybe every tweet could form its micro-community, and individuals could be banned by the original tweeter from engaging with that tweet, but not from engaging with all of twitter. Twitter must have brainstormed a million variations on this concept of a moderated community, and I wonder why they have landed on the idea that you should only be allowed to curate your own timeline and not that of others who follow your tweets.
