How about a web ring? A manifesto? A good name for it, or several? By that I mean things to make this distributed discontent more discoverable, and more importantly, all those neat little tools and protocols that achieve great things with a fraction of the resources while keeping the autonomy of the user intact.
We also need (more, discoverable) beginner level material that explains the beauty and potential of the web and many of its good parts (there are so many!). People who are as excited about the web and DIY as the Veritasium guy is about physics and math, and as talented at showing it. I certainly would tune in, and spread the word.
Wouldn't it be great if we could leave something to future generations, like people left us diaries and books? If we just keep shoving our "content" and personal musings into those silos, chances are very good they will get basically nothing. A big fat hole, compared to what could be have if we actually cared about our files and bytes, and got the average person to care about theirs too. I consider that literacy in the digital age. You don't stop at 20% literacy, that would be appalling.
And I posit it's not actually hard to become an adult, it's way harder not to. As long as you don't exercise autonomy it seems more and more daunting and hard, if you do, it becomes easier. I think the same applies here. There's just all these swarms of middlemen telling people it's all impossibly hard and dangerous (while they shovel on layers of complexity to make it so). They say don't bother walking, walking is hard, and offer to carry you. That goes well for a while, until you depend on them, until the idea of walking positively scares you. Then they start carrying you where it serves them.
