Twitter is not your friend. It is built to reward us for snarky in-group communication and designed to encourage unintended out-group readership. It fosters both tribalism and tribal collision. It seduces you into thinking you’re writing for one community but it gives everyone the ability to search your words and project them forward in time and space and outward into another community at the point when it’ll do you maximum damage. It leaves you explaining jokes that can’t be explained to employers that don’t like jokes anyway.
