agree with all items and wish to add: change witness voting rules to improve chain governance. and while I agree with removing social rewards from base layer, I think moving current setting to an ad hoc 2nd layer with same voting rules can be considered, since it's a waste to just let this 'global blog' vanish. My two cents.
Agreed on both points. We should see some improved governance in the next HF but I do think more can be done with voting, particularly vote decay.
