I've posted about this issue several times on the platform. But Steemit's #1 goal should always be to encourage new users to get to a "middle class" level on the platform, rather than helping popular authors make even more money.
The quadratic voting system is doing exactly the latter one, and it's for the worse. The issue is that they actually think this is a "good thing" and that popular users should get a disproportionate amount of the rewards.
I think that's a big mistake, and it will only encourage the majority of new users to dump the platform in the long-term. Plus, it will give Steemit a bad image outside of the platform, similar to how Digg got the reputation that it was "gamed", so people started moving on to Reddit, a much more democratized platform in comparison. Right now, the Steemit founders seem to be moving in the Digg direction, rather than the Reddit direction.
