I had a follower drop too but then it went back into the green this month. I don't put much stock in followers as unlike subscribers it doesn't convert to reads when people follow a lot of writers (although the subscriber system is also "glitchy" as I often see that subscribers do not receive the emails) , and many are just hoping for a follow for follow, which I don't do. I do appreciate when I see in my stats that I got credit for a new member follow and I have started rewarding writers that I hadn't followed with a follow if I read something of theirs that I enjoyed or impressed me.
