if they do not perform, they will not continue to receive upvotes and value out of Steemit.
However, we've seen time and time again posts that get handsomely rewarded for saying the same thing again and again. While it's not likely that he will get the 15k payout on a single post again, since he has now been hooked by the whales and followers luring him in to try and promote the site, he will still continue to get a nice reward, because some here think that his content is what will make them money.
It would be nice to know which users actually bring in the most new users that will actually stay with Steemit for a decent amount of time.
Will it be those that promote getting rich quick to people that will almost certainly not get rich quick, or will it be users that find content creators that are going to form the backbone of what makes something like this work.
Personally, I see someone getting 15k for a post and think that is like a pile on when you're playing football. Lots of people upvoting and rewarding past the point of reason. Meanwhile the share of the daily pie isn't going to the other users that certainly deserve the rewards siphoned off by the "big winners" of the day.
And yes, no matter what happens this is going to be a wild ride!
These are valid concerns. I'm glad we get to ride together to see how ti turns out :)
