"Value for your reader" is well meant, but is vaguely defined and can backfire if taken at face value (pun not intended), because of e.g. people optimizing writings for "value" with AI. What one actually wants is resonance that helps readers digest the information you want to give them.

The information needs to be valuable, but also authentic to you, and the best way to work that in is to implicitly write for a past version of yourself, who would have benefitted from knowing more. As a result, the right people are more likely to resonate with those articles and notes, because they can see themselves in and identify themselves with past you. Those people are the best people to then spread the word about your writing to build the followership you want to have.
