One other point on the EIP is that it might make content discovery better. But considering this is an app-specific blockchain I fail to see what that has to do with apps.

I didnt understand how that is going to happen? Will people upvote better content more? Will the bigger accounts stop upvoting friends and upvote other people? I have only ever seen a few curators do that and it is not easy being a curator. And ofc the curation teams like Dtube, Curie, OCD.
Why will normal people start curating good content now instead of just voting friends that will vote them back?
I was a curie curator for a couple months and even though it was fun at first that job is very hard and can get very boring.
