Coracle semi-randomly selects relays from people you follow in order to conserve resources. You can try increasing the "Max relays per request" setting to cast a wider net, but setting it too high may lead to flakiness. Coracle also doesn't query all followers for a large follow list. This is something I'm hoping to address soon. Let me know if the relay limit improves things!

Thanks for your answer! If I increase max relays, some posts change. I still can't see posts from my own relay (nostr.data.haus), which has some unique posts from a RSS gateway.
Any way to just use my own relays?
Not at the moment, but I have thought about adding the option. I'll look at adding that.
This is interesting, I assume nostr.data.haus has content you want to see, but not published by pubkeys you follow? The main feed goes by pubkey of your follows list, so it would make sense to miss out on relay-based feeds. To overcome this you might create a list with the relays you want to read from "globally" (i.e. without filters)
I've just released a fix for a bug that was preventing replies from people you follow to people you don't from showing up. This should help a lot, but the specific behavior you mention is still an interesting problem.
thank you for this explanation!
