I think it will take a bit from facebook because now we're incentivized to simply put great content on Steemit and only a catchy title on Facebook. Whereas before, we would spend more time on facebook's actual platform, scrolling down there and what was there all over the sides of the page we're looking at? ADS! See you later ads (for now) because steemit doesn't have em (yet). So that would take a hit on Facebook for sure.
