The other day I posted a Note in Substack with what I consider an important message. I’m linking to it below because, unlike normal posts, Notes are not pushed to subscribers, so most of you probably didn’t see it. The Note includes an expression of regret about one of my earlier posts, which had adopted what I consider an inappropriate tone. Whatever this Substack may be, I do not want it to come a venue for vitriol. There is already too much of that in the online world.
