A couple of things I would like to say....one a lot of what you propose for "The Last Network" are ideas I have proposed over the last year for Steemit....so I really like your concept. The name "The Last Network" though is atrocious, obnoxious and scary. Might I suggest rebranding the idea with something like "Shazaam" I suggest that name cause I thought long and hard about building a network very very similar to what you are proposing last year and after exhaustive research that name popped among the people I discussed the idea with. Oh and I already own the domain shazaam.me!

The network structure you propose, if I followed correctly, sound intriguing, but I think the possibilities of finding the famous people to start the networks top tiers is an unlikely scenario. Not to mention it, in the eyes of normal users, would look like they rich and powerful control the system....just the way it appears to people here on Steemit.

I think you would be far better off getting "relatively unknown" people to fill the top tiers of the initial network. You and the network would have far more visibility, distribution, adoption and support if people saw it was run and controlled by 10,000 normal people than a few thousand rich/famous people.
