Noticed very recently that after the end of available home feed ("Following") entries, "From Discover" entries automatically start. This is really ugly behavior that I hope I missed a preference to turn off; should've been opt-in.

Noticed some time after joining home feed entries expire, that is, one can't keep scrolling back to see posts older than whatever the cutoff date is; first posts I saw were no longer there. Is that fundamental to ATProto, or just the bsky.social app?
