These are some great posts you linked.
If you curate when the post is worth less than 16 Steem your vote gets hit with the 2e12 penalty similar to voting before 15 minutes, you aren't getting the full potential. However, once it is at 16 Steem curation % is shared with more people and it is similar to now where the people who 'discover' the content get a higher curation payout ratio. Curation is getting way too complext to explain. I can't see how people will jump on Steem and say hey this sounds like fun, I'd love to figure it out.
Moving to paynet is a great idea. I really hope delegation is not destroyed before Steem is a lot more evenly distributed than what we have right now.
It would be great if SMTs were up and running first. I do like steem-engine, but we are giving the makers of that a heck of a lot of power.
I agree the inflation with Steem is too high, but I feel suddenly dropping it would be a disaster. The post payouts would be that much lower if there was 2 or 3 % inflation and most people would be only making money if the price of Steem goes up. It would be a huge benefit to current stakeholders and investors, but until SMTs are up and running well it may turn off new members.
