I'm a big fan of the hardfork. I think the SPS will allow us to fund things that aren't priorities for Steemit, but that the community really wants.
I believe that the EIP is a good system, we've already implemented those components into PALnet and it's going well.
Pending testing and community feedback I'm planning adopting this voluntarily and would encourage other consensus witnesses to do the same.
