Recently I saw a post by @codenameone about a spike in follower-count.
I just looked at my stats and saw a similar spike in the last 12 days or so.
I already have 2,126 followers. Unfortunately that does not translate to more readers.
I published two articles during the week preceding that spike the had slightly more readers than usual. That might be part of the source of the new subscribers, but I don't see any increase in the regular view-count which is around 50/day.
There seem to be no correlation between readers and followers.
