There are already lots of places to post low value video. Basically, every social media site out there let's you post the home movie you want your friends to see and don't care if any stranger ever sees it.

I have a YouTube channel. It was created as part of an experiment that failed. I think I might have a total of 4 videos posted there. If it comes right down to it, the traffic I expect for my personal projects means I could just post any videos I create directly on my website.

And that personal website is where we need to get back to. I wish all the fancy programmers at Meta and elsewhere would just put their energies into creating the tools that let people put content on their own site as easily as on Facebook. Add some semi-structured data that can be leveraged by displaying the results of pre-built custom web searches and you should be able to approximate the experience of Facebook.
