In the client, you wouldn’t need to be sorting and running extensive calculations on all data. You could, e.g, build the front-page by indexing/scoring posts and comments that have been created since your last visit with a hard cap on some time window (last 48h) or total data points (e.g, keep only the most recent 10k objects in a local hot database, freeze/archive everyhing else.)
Absolutely. There’s a lot you can do. The “For You” Feed on Bluesky is quite instructive. https://bsky.app/profile/spacecowboy17.bsky.social/post/3mb2r5qei322a
But when you’re talking about sending a lot more data to clients, you really need to consider what that means for the internet bill of instance owners.





Good pitch. You could also ask people to help out with the more expensive computations. Say, adding alt text.
