HN and Twitter both have their dismissive assholes with their “You just invented ... buses.” (or taxes, or taxis, you get the idea)
But on Twitter you can block people and you can delete things easily. pg doesn’t write essays any more either, because now he has a hostile audience like with the Information, or when he said if you have a thick accent learn to speak English more clearly or when he said inequality is less important than growth and he got ragged for that. Writing in public is at best barely worth it for him with his greater profile.
