RE: Earning from many instances of the same

Interesting insights.

And because this is blockchained, there will be a reference to every shared instance that has been made that all ties back to the original instance, no matter where it was created in the ecosystem.

Yes! Accountability, plus credit and rewards also go to the original creator.

... the community are going to bring content in from other sources to better service their user base, and the user base will of course do the same.

I agree. Content will have multiple "natural flows" to where it's relevant/appreciated.

On this note, having a feature that allows mods/admins to resteem stuff to their communities sounds like a good suggestion to make.
