What Smooth did was actually a very very good thing. There needs to be a few influential users willing to bring concerns to all of our attention so that we can ALL discuss things before someone absconds with OUR shared rewards. Giving extra money to one user is taking it from all other users. I understand that this isn't obvious when you read the various posts explaining how rewards are distributed and created, but it's still the case. Giving 10k for Steemy the astronaut takes away from the amount @jumpman and all other users make.
When you see your post going down in value, it's not only due to the fluctuations in the currency it's due to some other user getting paid more due to his increased percentage of the daily reward pie.
There are a ton of posts that "could" be trending on any particular day due to the whims of the whales. This app and it's post, which looks perfectly fine to me, could very well have made only 1k or 5k or 5 dollars, just as any number of other posts have. It doesn't automatically deserve 10k, just because at one point the rewards said $10,000.
There are indeed a number of less than stellar quickly created and downright bad posts that get a lot of reward, but that is no excuse to pay something more than it's worth now because of errors of the past.
