You do make a good point in regards to crap. Quite often we'll stumble across something that's rewarded highly and think it's crap, or overvalued. Yet someone thought it was worth it for some reason.

Many sites have similar problems. Take Ebay. There are tons of things that are either intentionally or not, miscategorized. Ebay doesn't have an option to report something miscategorized. Sometimes when something is in the wrong category and I'm annoyed enough, I'll actually message the seller to tell them. This happens most often when I see something labeled to be in my size, that isn't. If I mistakenly bought it, that would be a big mistake, so I message them.

The way Hive currently works, you have to post in a community, and if you post in a community, you have to repost it to your blog. Honestly, it's really dumb. Posting in various communities can mean you get a lot higher upvotes. Posting in no communities may mean you get next to no curation. What if you wanted to post in multiple communities? It just doesn't work.

I think the communities need a rethink, which may be difficult since we're working on a blockchain.

What you bring up has an interesting point. I'm not sure if there is enough categorization that needs to be done for it to be highly rewarding, but those that do it should be rewarded, and I have a feeling it is necessary.
