I'm not really sure if you are trolling but come on. The content that gets voted up for most part is the most popular stuff. More people think it is the best quality, or at least most of-interest to them. Take follower count for example, which presently has no reason to be gamed in this system (though elsewhere in social media it does and I'm sure it will here). @dollarvigilante has almost 3000 followers. A lot of people here like him and think his work is quality. So when he gets voted up that is exactly quality work being voted up, even though it happens in practice by a combination of people and bots (controlled by people). Similar comments could be made about @gavvet, @charlieshrem, @heiditravels, etc. Even @msgivings who was a highly divisive author and had an issue with plagiarism, was widely followed and her posts consistently had very active comment sections. People here like them and appreciate their work.
If you think you're the next Bethoven and your musical symphony scores are top "quality" and should be voted up, well you are one person who thinks that, and you might even be "right" in some philosophical quality sense, but the system is unlikely to reward you accordingly if no one else knows about you or cares about your work.
Now if your issue is that whales control all the stake and have different opinions about who or what should be voted up than you do or some other users do, my answer is the same as it has been every time this has been discussed: We need to redistribute the stake (via selling).
Finally, if your claim its all bots and nobody actually likes the stuff that gets voted up, I disagree. See above.
It is a game yes, but it is a game that results in the most popular authors and content consistently getting the most votes, along with fairly consistent successes from hidden gems. That's both the intent of the design and the results we see in practice (again see above). Is there a better system that exists? I doubt it. Go post on Facebook or Twitter with no followers and see if you have any significant chance whatsoever to get a lot of exposure (you don't). At least here there is a constant ongoing effort (because that effort has the potential be rewarded) by those who are digging through hundreds and thousands of junk posts to find a few that look like that have a lot of potential and voting them up, which in turn starts to give them exposure and shot.
