It's really the curation that needs to be taught to everyone. A big dose of critical thinking skills is what we all need, because in earlier times you could tell the crappy ideas by the way they were packaged: crazy guy at Hyde Park Corner, dude with a megaphone shouting out passages of the bible, crappy home-made flyers. You could work backwards from "nutter is probably wrong" to why he was wrong. Part of why this worked was because it cost something to publish stuff, and so publishers would have a think about what they wanted to spend their resources on.
Nowadays everyone has figured out how to package the message, and it's super cheap to do so and get it out there. (Incidentally, actual packaging is the same now, crappy products used to come in crappy packages, but no more.)
So now to pick apart an argument you have to be a bit more aware of the actual content, and it's a bit harder to get to the bottom of BS.
Curation is the first step, but we also need more organizations who take on the job of keeping some bits of the internet from going dark. Especially for things that were originally done for the common good.
There's a local group here that basically specializes in devops for little public projects that have run their course. They even do a little bit of work trying to provide templates for new projects (eg, for a local hackathon), but I'd like to see them go farther.
Bigger, more national or international groups that come up with recipes for projects where they say, "If you build your project on this structure, then we will be more likely to run it for you," I think is a reasonable logical next step for the Internet. Given the task of running 10 projects that 'need' 4 servers each, it would be very good if I could do it all with 20 servers, not 44 (40 + orchestration machines).
We don't have a "PBS for the internet" but then PBS didn't always exist either. You need a beach head of some sort to even propose such a thing to government.
