This is actually the first time that I see someone addressing the concerns I directly had when I started with Steemit.
I really believe that all treats together could kill Steemit in the long term. I think you can see that from the number of accounts becoming inactive, which is really HUGE. Maybe you should have a look at that also in this series?
If I do some calculations, I end up with the average reward being 1/36 of what it was less than 1 year ago. So my average Post now gains like $0.03-$0.12. 1 Year ago that would have been $1-$4 😳
