"Nature allows paid subscribers to place any article in a flakey peephole viewer which usage is reserved to the ones who registered an account with Nature and agree to use some DRM-filled proprietary software".
"One day" will come when free and open-for-everyone platforms will occupy that domain, not when "Nature" or some other sly organization will do that. Like archive.org, but with peer review by people who use it.
I'm sure that in principle it is possible. I mean, if you are interested in some domain you surely know few people who's opinion you'd trust. They might not even be Ph.Ds, but they somehow got this good reputation, probably not by accident. So if somebody like this presses "Like" button under some article and leaves comment about what is trustworthy here and what isn't, it probably will be as good (better, actually) for you, as opinion of Nature's staff. And as these people by definition are interested in this domain as well, chances are they also will be interested to read this article and thus will be able to press "Like" button and leave a comment.
So, yeah, in principle it it possible, but I imagine it is really hard to do it right. Because essentially it is the same as any "karma" or "rating" system on some forum, and inventing proper rating system is really hard — it's not the most knowledgeable people who usually have the highest rank on any thematic forum. But on forums and other existing social platforms it works, because rating isn't that important. And in our case it's all about rating and trust.
