I completely see your reasoning there and that is also another problem with this platform.
That is there are valuable posts that didn't get seen in a certain window of "time" and thus there is less incentive to UPvote or maybe even incentive to NOT vote.
So I can see some of why this works and all in all love Steemit and would keep using it even if it didn't get better. Yet my hope is that it gets a LOT better. That there are people who have great ideas, those ideas are supported and upgrades are made and the community as a whole is better.
The problem then of course is that not everyone will agree on everything...EVER. hahaha so it is possible that many agree on a lot and thats best case scenario.
If the platform works the way a lot of people want it to then even though some don't like it enough do to keep using it thus it is "successful".
If it doesn't then it won't get used. I hope that not only does Steemit stay awesome but get more awesome.
Eventually someone or more likely a group of people will develop something even better. Those who can adapt are the ones ahead of the curve~*~
