Hi @southernwolf, personally I'm not in favour of as big a change as 50/50 reduction in author/curator rewards, nor am I a fan of deducting as much from the content rewards for the SPS funding, I feel more should be taken from the SP interest which no external investors even know about and 1% from witnesses as a show of solidarity. The other changes are great, the free downvote pool is awesome, but should have been delegateable. The SPS worker proposal system will be good also in itself to lure developers to Steem in search of funding for their idea.
I invite you to have your say in a structured forum discussion on https://neosteem.com/topic-list?category=hf21 it will be easily referenced there for all users, mitigating the need to comb through separate posts to find discussions.
