Yeah I've never used medium myself but I don't doubt it. I hate when I see a really well rewarded post with 0-3 comments on it. I'm scraping pennies together with some of mine and can top 15-20 comments. Financial reward on some of these posts doesn't make a difference but it's just crazy to see it sometimes.
I know that some platforms only really get a lot of interactions with politics. 4chan and Reddit come to mind but probably Medium as well. Kind of odd if you ask me but then again it get's banned like the President does on the other platforms lol.
