Richard MacManus, of ReadWriteWeb fame, has an interesting analysis of email newsletter subscribers that gets into the question of whether or not people are willing to pony up for paid subscriptions, and if so to what are those willing customers subscribing, exactly. He talks a bit about the idea of “subscription fatigue” and as I’ve wondered before if “you could subscribe to all of The New York Times, The Washington Post, and Medium for $17/month” why would you instead spend more than that to subscribe, for example, to just five SubStack newsletters? You’ve got to have a lot of casual cash sitting around to subscribe to anything more than a couple.
