Then we agree on the diagnosis. What I keep coming back to is what actually moves somebody from reading here to writing here. For me it was mundane: a person replied to something I had written, and that was the whole difference. The unit that compounds is the follow, not the post. A post from nobody is a note in a bottle. A reply from somebody with an audience is a loan you pay back with something worth reading. So the work stays small and unglamorous: be readable without an account, answer strangers, keep the good arguments where a search can still find them years later. What made it stick for you?
