I'm really enjoying lemmy. I think we've got some growing pains in UI/UX and we're missing some key features (like community migration and actual redundancy). But how are we going to collectively pay for this? I saw an (unverified) post that Reddit received 400M dollars from ads last year. Lemmy isn't going to be free. Can someone with actual server experience chime in with some back of the napkin math on how expensive it would be if everyone migrated from Reddit?

I don't believe this is how it works though.

Let's say your tiny 3 person instance is connected to a big one. I believe it only pulls in content from the communities somebody from the small instance is subscribed too. Correct me if I'm wrong.

That's what they're saying.

Essentially - if someone from the small instance subscribes to a community that has a ton of data (huge post volume, images, whatever), the small instance needs to pull data over from the larger instance. At some point there may be communities that are so large small instances can't pull them in without tanking.

maybe I phrased that poorly and you didn't understand what I was trying to say. The size of the bigger instance shouldn't matter at all because only data from communities is pulled, that a member of the smaller instance is subscribed to. So if the bigger instance has 1000 members or 2 million members wouldn't make a difference. The only thing relevant should be how active the communities are that members are subscribed to.

Sure, the sizes of the communities is what matters (multiplied by the number of communities users on the server care about).
I think most of us are assuming larger instances are more likely to host the larger communities.

Actually, if I'm reading the protocol right, it'd be hard for a small server to host a highly active community anyway (for some value of highly active). So yes, some 2 person instance that was created to offload stuff could be the primary host for a massive community, but in practice it won't.

We are arguing about very specific things here anyway. And I generally do share your concerns about how well this is going to scale. I want this to do well.
