Interesting. I'll be sure to have a look.

By the way, did you know that you can automatically notify users of Medium by naming them in a special way in your article? You type @Joe Shmoe in your article and pick the name from the list that appears. The name turns green and Medium will automatically notify that person when your article is published. That way you don't have to drop hints like these in the comments. I recently learned of this feature only a few months ago.
