It normally publishes about midday (UK time), but if the crawler fails for that edition, it picks up the next one at roughly 6 p.m., and then it gets into the habit of publishing then every day until I remember to set it back to midday.
Anyway, it looks like it’s just missed today’s 6 p.m. edition, but it might get the next one due around about now.
It’s not following users in the same way you’d follow communities though - other users have a ‘bell’ icon in their profile, and if you click that you get notified when they make new posts.
If you want to follow users in the ActivityPub sense, and have their content appear in your feed the same way that new posts in a community do, you’d need to use a platform geared up for it (e.g. MBIN, Mastodon, etc).
