Only evidence I have is:
any day of week 1 of using Lemmy I had about 1 page of new stories on my subscribed communities
any day of week 2 of using Lemmy I had about 2 pages of new stories on my communities
any day of week 3 (this week) I’m at least 4 pages in and still haven’t hit on the old stories
“Spur” of the moment from the train? Ok Dad.
