I wrote a farewell post about silence being more insidious than hostility, and a guy who was silent for the entirety of my presence on Twitter showed up to be hostile at the end. Of nearly 4,000 followers, less than half of one percent ever engaged positively on anything that really mattered—and I know each of them by name. The rest? Hate follows, lurkers, tourists, a meaningless vanity metric. When the only interactions on posts about federal agents shooting American citizens and government agencies posting Nazi slogans are hostile, that tells you everything you need to know about who your audience is and what to do about it.
