I do this as well. I am not perfect, but I try to avoid making too many mistakes, and editors at times have missed the ones I have made. I understand your view V, however, I must say that I have discovered that not all writers on Medium have the same skill set. Some people on Medium don't consider themselves as writers, some write as a hobby or just to vent, and I find those articles usually do very well. There is no clear way to really predict what works on this platform.
