Um. The problem with current system is that content creators get very little. That is, they produce value, but have only little say how monetary reward is distributed. Communism is about breaking the monopoly on production, and here on steem the production of reward is curently ultra monopolized, but it aims to be a decentralized system. For it to be so, it could use a little communism.

I understand that people have been condition to react to the word "communism" as something bad. But thing is it is a part of the anarchist principles, but to understand how you would have to first deprogram this conditioning and form an opinion of your own. The aim of communism is to reward those who produce by the way of ending exploitation of man.
Thing is in a lot of places it failed because of the external pressure. The best example of "communist" experiment was project Cybersyn in Chilie, that performed admirably, before being shut down via US backed military coup. Thing is it was built on the cybernetic principles which are the cutting edge of planning and management. :->
Also do read on Anarchist Communism especially about gift economies, like free software.
