Riu, really enjoyed this. Such an interesting experiment. I will have to try it myself. It does give some valuable insight about what "Top Writer" really means and how valuable it will be for writers as they continue to grow on the platform.
In the near future will it be about "followers" or the quality of the "followers?" Followers who are engaging with your content have the most effect on how well you succeed on Medium.
Thanks so much for your investigation. It's given me a lot to think about.
