Then they can build on the EOS.io platform like the https://everipedia.org/ project with there IQ token they airdropped on the EOS token hodlers. I think the eos blockchain may be a better suited for this project than the STEEM blockchain. Just by the nature of the way the tokens lock up the storage space on EOS and such. Techincally one could build it on STEEM and yet it is life right now and will have a much wider audience on eos.io

I am not sure how to deal with the gang issue you refer to on the concept of the blockchain as a city. I think steem is just the first in a long long line of platforms that will allow communities to grow and prosper on there own different chains. I just see it hard to beat eos so I think the witness will end up running steem on the eos platform. Thanks for the reply and I hope the link provided can help you in your idea of a pedia on STEEM at least to see how someone else is approaching the solution, oh the co-founder of Wikipedia is on the Everipedia.org project.
