Interesting stuff.
The burden of building not just a community and a technical platform, but also a novel cryptosystem and supporting economy, is extremely high.
They're right about the strain on the lead devs.
Creating a brand new system ... with all that pressure, and people's expectations/hopes ...but I think that will be solved by the community contributing - and we can clearly see that happening, and also other Steemit offshoots developing healthily from the new blockchain.
Good luck to them, I say.
Each to their own.
Love Peace & Freedom.
