Unhappy with algorithms

I've noticed that the Youtube algorithm seems to refuse to notify me in the "recommended" category about lots of new videos by people I follow.

Also, it's very hard, it seems, to get Bluesky to show me all new posts by people I follow, even if I am using the "following" tab/feed.

I mean, I did manage to get Bluesky to recognise I was not interested in digital art and amateur anime drawing.   But in the Discover tab, it insists of showing every single post by a handful of people who I do follow, instead of just some of them, meaning that there is not that much space to "discover" anything.

I guess, in other words, the issue I have with Bluesky is the opposite of that with Youtube.

I only just realised that by making this post.  See - writing things down helps.
