I think we missed each other. My overall point is that aside from the hosting/serving, other federated networks/services could pick up the slack. The Federated Youtube doesn't have to mirror Youtube exactly, or even mirror functionality all-inclusively (ie with reccos and comments etc. built-in), but could lean on other federated servers to provide similar functionality.

As I said, comments could be a lemmy/mastodon thread. Recommendations or other discoverability could be other threads or maybe even a completely different service that hasn't been created yet, I don't know, but I do know that any reco algo needs to be open and subscribed to, not jammed down our throats and gamed. In the meantime, everyone's got a search engine, right?

Ultimately I don't live in this social media/open source/development space too much, I just saw a way for these things to be built/used together to achieve an effect, distributing dev and process overhead and load across all the networks. I don't have any insight on the bigger, more pertinent, file distribution problem.
