well, legit, non-tainted, non-spook-handled citizen journalism is very important.
nostr will give you easy access and probably if the stories are interesting, a lot of people paying attention. if video content is the thing, you just need a way to host it. someone here will have ideas. there may also be existing projects you can get involved with.
there is a lot of devs on nostr. and we need both content and testers. you'll find what you need, i think.
