A very good point, but -- ironically -- not very clearly stated. Indeed, most HN commenters seem to think that this piece is about advertising. It is not. True, that is the primary example used, but later he talks about writing novels. The point (as I understood it) is this: give value to your readers. No one wants to read something just because you wrote it. They want to read it because they get something out of it: fun, information, etc. And brevity & clarity mean your reader has to work less to get the value.
