@ned glad you're thinking about these things, though I generally agree with @smooth (1 could be interesting, 2 is a bad idea).
The big thing that Synereo and others are thinking about to disrupt Steem is more "fairly" distributing rewards to good content creators. If they do this, then they've got a shot. If Steem continually improves at this to the point where the majority of good content creators feel they're adequately rewarded, I don't think Synereo has a shot.
