You're highlighting many of the reasons why I was in support of a linear rewards curve. Unfortunately it didn't work out that way and it was just gamed even more. Yes, the little guys will get very little. It will go back to being more like a lottery as originally designed and as outlined in my post. I do think more of the reward going to curation combined with the ease of downvotes (and hopefully tooling to make content to downvote easier to discover) have the potential to change things up this time. We'll see.
