Thanks again for sharing your thoughts.
I have just started to write on Medium in English around three months ago. Before that I was a reader, only.
I still have to learn everything.
There is one thing that I find noticeable:
I have only one article that was "chosen for further distribution".
Then the new rules of Medium kicked in which said that they will not choose articles for "further distribution" any longer.
So I see only one article thrive and all the others - not.
This one article made half of my income last month.
So, I guess that might be a partial answer to the decline.
I still hope that everybody will figure out what and how to adjust to be able to continue publishing here.
