If rewards were shared equally amount all curators, that would be a much different issue. Likewise, if those members with higher reputations did not have any more downvoting power than lower reputation members, that too would be a much different issue. Downvoting other members simply because you do not agree with what they have to say, has absolutely nothing to do with maintaining a quality forum. In fact, quite the opposite is true. The quality of the Steemit forum is extremely low for that exact reason, because serious social media people will have absolutely nothing to do with a platform such as Steemit.

If Steemit was designed properly, it would have perhaps 100+ million members by now, but as it is, it has only managed to attract a mere 1 million, with less than 5% of those still active.

I agree.
