Great piece of work @justineh

You nailed it.

My strong impression is that in order for HF21 to be succesful, we would need more so called "whales" to delegate some of their SP to those who actually (manually) curate content. That would encourage curators to be more active.

Will that really happen? I hardly doubt so. I think most big players will "milk the cow" and will focus on short-term gains.

Also from my understanding - current non-linear reward curve will affect those with small voting power and will discourage those who actually upvote valuable comments. 

> But what about those just spamming and upvoting themselves? 

Assuming that Steemit Inc doesn't support self-upvoting, then why wouldn't they simply switch off this button? My impression is that self-voting is being fully supported by them. After all why we should only be able (as curators) to curate content of other people. Why shouldn't we be allowed to curate our own content? 

Some people are okey with it, others are against. But bottom line is that this option could be removed by creators of Steemit. And they clearly do not want to go that road. So it's fair to assume that self-voting is being accepted even by those who created this platform in the first place.
