Just to help establish the current facts ...

They don't and ours aren't.

That's not the way we build our web of trust. We look at a person's entire zap history and compare it to everyone else's. A web of trust based on follow lists can be called a web of trust, but the resulting web is not the same as ours.

The problem with #1 isn't that it's impossible. It's that it takes a long time to gather and compute scores for events and to gather relevant events and re-order events.

This kind of thing will be remedied somewhat by clients storing more historical data in clientside relays or things like nostrdb but Primal is still going to serve the current version of your feed faster (because they built it while you were offline) and Nostr Band is going to perform thorough searches more quickly (because they gathered all the data while you were offline).

I'll be more optimistic that this is remotely as easy to do as all The Sayers say it is when clients stops using megarelays to provide algorithms and search.
