Not to mention that it drives your users away and reduces your conversion rate by showing them a big full-screen banner in front of your posts every single time they visit the site unless they sign up for Medium themselves. Who wants to have to log in just to read some blogs?
And then there's the lack of RSS feed, so I have to actually visit each individual blog to see if there are updates instead of having them dropped nicely in my inbox with the rest of my morning read.
Medium is a garbage place for readers and content producers: please stay away from it.
