Relevant discussion last night on Medium: https://news.ycombinator.com/item?id=5968593

Also last night, I made a quick graph on medium.com submissions to HN, containing the top 20 posters by number of submissions, for 1000/1315 links containing the medium.com domain: http://i.imgur.com/WIJ4cT9.png

It's also worth noting that out of those 1000, there were only ~650 unique submitters, implying that most HNers only submitted one medium.com article. If anyone is interested in a more thorough statistical analysis, I can write up a blog post. (hopefully with better graphs)
