There are many complaints sometimes also well justified. For sure Steemit is far from rewarding content by its quality, more important is how much SP you have and what communities you are part of. Dead cat photo can make hundreds and an educative and quality article just 0,1 We all know that.
Auto-bot voting, self voting, Auto-bot comments...the lack of private content, the lack of communication options like private messages, constant notification problems....... the list is long. These things don't help the Steemit platform to become more succesfull. Look at the market, other coins going up but Steem not really in last weeks or so.
This is not an complaint. I like Steemit and that s why I am here, however there are things that I dont like and will need to change in the future IMO the platform wont success otherwise.
