Wow, that's so well written and so insightful I'm afraid to even attempt my own post on this subject; I think I'll just comment on everybody else's this time..

5 - love it - I would say SMTs open up so many cans of worms, I would have to agree.

SMTs:

• Just one more distraction... from showing the world what a great new model exists for the internet?
• Or the way forward for the Steem blockchain to show the world how much more powerful it is than previous generation BCs that came before it?

I would also have to add, I hate ads. But I know there is Mucho Dinero involved. Mucho Trillions Dinero.

I do agree; FB is watching; and they will make a move at some point.
They are looking down the barrel of a potential model that can replace them. What do they do about it?
