I think many people have made friends with other people and they regularly upvote each other. There has been a shift in the culture but it will have to continue if we are to see valuable posts consistently getting good rewards and shitposts getting nothing.
Changes to the blockchain protocol may also help a great deal. If curation is even more incentivized, then less people will blog and they'll focus on curation instead. And people will blog if they have something valuable to say. Or at least we can approximate that outcome more and more with better protocol rules.
When I go to my homepage, I feel good. Because there are really useful posts coming in the trending section. But when I go to certain communities, I feel uncomfortable. It seems they are not doing what they should be doing.
I'm afraid if the number of shit posts and rewards for such shitty posts increases, it will not bring good output in the long run for Hive.
Thanks for your time!
