I couldn't agree more. If Steemit implemented some kind of site-wide affiliate program (like with Amazon or Overstock.com) and the proceeds were split between Steemit.com and the author+curator reward pool, then everybody would win. If individual authors are in perpetual, atomized competition with each other for ad revenue, everyone does not win, and the overall benefits of advertising to the platform and the people that use it the most would be minimal.
