The two major ways currently used for curation seem to be 1. aggregation of some measure of approval (upvotes on HN, likes on Facebook) and ranking based on that, or 2. sharing with contacts (retweets on Twitter). You could try combining them and would likely end up with something similar to what ttoinou suggests in a sibling comment (https://news.ycombinator.com/item?id=15734474) [Which I have thus curated. Funny how that works.]

I think those measures work very well. However, they apparently don't promote enough of the content you like. But that's not the fault of the curation mechanism, it's due to the preferences of the curators. Most people just aren't very interested in "truth that is healthy and right".

It's very easy to use existing curation mechanisms to filter out most of the stuff that doesn't interest you (I have never seen an instance of the "fake news" phenomenon); but you aren't going to get everyone else to do the same.
