I've run into that issue, didn't know if it was just me or if others had encountered it.
I think if Steemit did give notifications of follows and unfollows, a lot of mindsets on the platform would be different. Small things like being followed, likes, unfollows, etc. can easily uplift or break most people on the interwebs.
I'm actually surprised there isn't a rant tag.
