As long as steem uses global metrics, you will get the kind of crap everybody wants (weighted by their influence)
What could improve situation is having metrics computed for your personal tastes ideally, if not that , then for cluster of tastes close to yours, and if not that, at least for category of the post (or each tag it contains)
One of approaches that might push things in more interesting directions:
improving-steem-s-rankings-to-cater-to-diverse-content-preferences
That would be a great idea! However I wonder how this might affect new users posts visibility. Right now there are lots of people viewing the new post thread. I think that's valuable and a tthe same time tweaking the taste settings would be great too.
