The brilliant thing about text on the internet is how easy it is to publish it, comment on it, and share it. Medium is a posting platform designed to make it easy to publish long-form articles as simply as possible. They’ve taken the idea marginalia and made it a reality. The point of Medium is to focus on the text, without all the bells and whistles. You’ve probably read a Medium article before without knowing it; Medium is about the content, not the platform.
