My standard joke about my job is that I am less a “writer” than I am a “textual YouTuber for Gen Xers and Elder Millennials who hate watching videos.” What I mean by this is that while what I do resembles journalistic writing in the specific, the actual job is in most ways closer to that of a YouTuber or a streamer or even a hang-out-type podcaster than it is to that of most types of working journalist. (The one exception being: Weekly op-ed columnist.) What most successful Substacks offer to subscribers is less a series of discrete and self-supporting pieces of writing--or, for that matter, a specific and tightly delimited subject or concept--and more a particular attitude or perspective, a set of passions and interests, and even an ongoing process of “thinking through,” to which subscribers are invited. This means you have to be pretty comfortable having a strong voice, offering relatively strong opinions, and just generally “being the main character” in your writing. And, indeed, all these qualities are more important than any kind of particular technical writing skill: Many of the world’s best (formal) writers are not comfortable with any of those things, while many of the world’s worst writers are extremely comfortable with them.
