We once glorified Twitter as a great global town square, a shining agora where everyone could come together to converse. But I’ve never been to a town square where people can shove, push, taunt, bully, shout, harass, threaten, stalk, creep, and mob you…for eavesdropping on a conversation that they weren’t a part of…to alleviate their own existential rage…at their shattered dreams…and you can’t even call a cop. What does that particular social phenomenon sound like to you? Twitter could have been a town square. But now it’s more like a drunken, heaving mosh pit. And while there are people who love to dive into mosh pits, they’re probably not the audience you want to try to build a billion dollar publicly listed company that changes the world upon.
