Hi Tony, I'm someone who followed you recently. It's fascinating to hear how you are getting to grips with the task of Medium CEO.
A weekly newsletter is a great idea. It will bridge the "divide" between writers and those (till now) faceless people who run the show at Medium. For instance, one of the biggest complaints I have heard from writers is how much of a "Black Box" this platform is. Sharing insights, as you evolve into your role as CEO, will do a lot to dispel the mystery.
So thanks for making this commiment to two-way communication!
