In my experience, medium has a lot of resources about Deep Learning written by different users, and they implemented as a company a recommendation algorithm for their articles, which i liked it very much.

With just a google search i did, medium + recommendation algorithm this article appeared [1].

Also if you haven't tried medium's recommendation engine, i strongly suggest making an account and ticking a box somewhere for email recommendations.
