Hi Tom. I used to get 30–40 new followers a day and now I get one or two. You have to look at the quality though. I think I was on the suggested list for new users. Most of them hadn’t set up a profile and I would guess that many of them might not be active now.
However, my one or two followers a day that I get now are Medium regulars with an established profile. These people are going to stick around.
I think with the partnership program there is more promotion of paid articles than the publications.
