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.

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.

I really don’t understand the benefit of being federated

The benefit is to prevent this from being the next Reddit. Being a nonprofit doesn’t really guarantee anything in the long term. OpenAI was a non profit and now it isn’t… Rather than trust a single entity to not abuse its power, federation aims to not give any entity all the power to begin with.

It also solves practical problems. Which single benign entity would pay for the servers and internet connections to become the new reddit? I don’t think there is one.
