Sounds interesting @timcliff although the technical bit is a bit above my pay grade. I do feel, however, that more people being able to contribute would be helpful.
When you say 17/21 witnesses are you reffing to the 21 witnesses that appear at the top of the table? Do the ones with less power have no say in how the blockchain is developed?
Thanks for the SBD/Steem payout ratio information. I was asking another witness about that today so now I don't need his answer. 😁
