Peertube is federated. It seems to work similarly to Lemmy. I went on a random instance and clicked “discover” and noticed that I see videos from other instances. So at least the hosting cost is distributed across instances.

The other issue then is the bandwidth. Peertube uses p2p among viewers, so if there are many viewers at the same time they can take a significant load off from the server. Instances can also cache each other’s videos to split the bandwidth cost between them.

I think these design decisions means that it is possibly viable, though it is definitely way more expensive than non-video federated communities.

Full-time creators need to be paid, but it doesn’t have to be for watchtime specifically. There are already services and creators on the web that make a living via patreon or other donation systems. And there are small-time creators or creators already backed up by funding that don’t care about monetization.

I don’t think such an aggregator is required. Interoperability is smooth enough that you don’t have to think about different instances most of the time. I’ve only really noticed two points that would be confusing:

• the sign up process
• the “local”/“all” distinction

So I think what we really need to do to make this platform intuitive to people that aren’t already familiar with it is:

• Somehow streamline signing up. The process from googling Lemmy to having an account on an instance should not be confusing or intimidating.
• Filter by “all” by default. The default should cater to the users which are less likely to figure it out themselves. If you don’t understand what instances are and what “local” vs “all” means, then you are probably here for the “all” experience. If you understand and really want “local” you are probably fine having to set it yourself.
