SUBSTACK, A HOSTING and publishing platform for email newsletters, took what seemed like an innocuous step last week: it launched a standalone smartphone app. Not surprising, perhaps, since almost every content startup has an app. But Substack’s app is a little different, since the company isn’t offering a service directly to users, but instead is a middleman that stands in between writers and their audiences.
