Mark Zuckerberg wants the entire world but even he, didn't take cognizance of the entire world in the creation of the Facebook model; to where nations are simplified to represent locations.
Mark Zuckerberg model was a fairly construed one, though giving chance of participation to the untalented but with a very unfair sense of not belonging. All was centralised into a one man's vault. Though he may not intend this this way. But i think his model did. This make me to agree with the second part where you stated below.
Well, i am not with him and i don't know him but i know life and humans very specially and he is not from outer-space and yes, he may have wanted to (take cognizance of the entire world in the creation of the Facebook model) but he can't have Mathematically or scientifically been able to, because there are other parts of the world where there is "donkey life" and "donkey life" is a hard concept to grasp.
The Blockchain (steem) was able to figured out the barrier and broke it through decentralisation - leaving every participant with the sense being part of the system.
The steem world seemed a bit complex with the real world attempting to see the talented in multiple of 7, leaving the otherside with just 3. Steemgigs surpassing all reach - giving hope to the untalented; where everybody is a winner.
