I think OPML is the technology. Go build one and share it. Writing or recording your own stuff is a lot of work. Help promote all the cool things you've found outside the walled garden of plastic plants.
Build a website for someone, teach them html for 20 minutes and set up a domain, hosting and an ftp client for them. They can always call you if they get stuck.
People should be able to host things on their computer and without having to learn anything. Friends should archive and mirror it and without having to check boxes.
Only with file sharing the establishment went to war. Maybe ipfs will grow to that level.
