Since there is little competition
The reason there is so little competition is that only a tiny portion of stake can earn decent curation rewards with the total as low as 25%, For the vast majority of stake, the return from the 75% vote selling/bid bot/self voting share is always going to be a lot higher. That's simple math; it can't be any other way.
With curation boosted to 50% (along with the other changes) the math changes dramatically. The contest between curation and selling/bidding/self-voting at least then starts out even and not stacked 3-to-1. But the economics changes not only due to the 25->50 and 75->50 shifts (both are important here), but because dumb curation bot votes on mediocre or poor content that gets overvalued (as well as attempts to revert to self/paid/bid voting) has a greater chance to get downvoted, seriously harming the ROI, further pushing the balance toward good curation. But more importantly, the overall economic changes will likely shift tens of millions of dollars worth of stake from dumb voting to smart voting. The talent that will be brought to bear (both in terms of talented human curators and smarter bots) will be dramatically different. (Think NBA vs. neighborhood pick up.)
This is a huge change from the status quo. Not every aspect of the outcome can be predicted (it never can), but extrapolating from the current situation rather than thinking through the economics from first principles is likely to get things very, very wrong.
This is true, so let's look at higher curation rewards in action: Another advocate of 50% curation rewards is @heimindanger. A few months back, @dtube launched an experiment where they would take 25% beneficiary rewards and redistribute them to curators, effectively raising curation rewards to 43.75+%. The huge DTube upvotes on manually curated videos further raise curation rewards on good content.
Did it result in a huge increase of manual curation on DTube posts? I honestly don't know, it would be interesting to compare the curation activity on DTube posts with and without the raised curation rewards. From the fact that DTube has discontinued this experiment a few weeks ago I assume that it has not had the desired effect though.
The huge dtube upvotes distort the whole thing in my view. I can't really tell if anyone uses these apps (or curates their content) because there is real demand for it, or mostly because there is massive free delegation subsidizing it all. Is the game really about 'curation' or is it about catch-the-delegation-money?
Bear in mind that the goal (particularly of the poster here) isn't necessarily manual curation per se, it is changing voting behavior to be less content agnostic and less focused on self-enrichment with no real contribution. That could be manual curation, but mostly it means making the self-voting type stuff unprofitable so people stop doing it. If they instead delegate to even a mediocre (bot or human) curator, that is still better than self-voting and vote-selling (at least according to the poster, but I would generally agree).
As for discontinuing the experiment, the obvious question to ask is where is the money (which, again, is largely a game of catch-the-free-delegation-money) going now and why was that decision to move it made? It wouldn't necessarily need to have anything to do with the curation.
There still might be useful data there, I don't know.
When does the mined stake take its thumb off the content creation scale, and its profits solely from price increase?
I was reminded, again this week, that my content doesnt pass the conformity bar set by delegated stake.
We still have to suffer from the snobbery of centralized control on a 'decentalized' platform?
