You finally receive a one-star review in Apple podcasts (or some other app). There are those that say you are not a true podcaster until you've received your first one-star review. Do they hurt? Sure. But in some cases, the reviewer may have a point (if your volume is too low, too high, or fluctuates) and that is fixable.
This video is not about that person. This video talks about the person who is providing constructive criticism (and there is a reason for that) -and there is a reason for that.
