I think that the most important thing is needed: "more users".

Indeed. Problem is: The like the super-linear x² reward curve and free downvotes is very unattractive to new users and offsets all the good stuff.

better distribution of the rewards well

I'll have to disappoint you here: With the super-linear x² reward curve rewards will not be distributed more evenly when new users join.

We must not cease our efforts to promote the platform and make it popular.

But I can't, with good conscious, promote Steemit. Not as long as there is such a huge bias towards the whales.
