X algorithm is the most tunable I have come across.

I can mute all words I don't like to see, and hit a bunch of "Not Relevant" once a month or so, and my X feed has only relevant content. And it has very high density.

I like the vibes of Fedi, but not enough density.

And Bluesky is just Old Twitter 2.0 without the density of technical stuff. That's the default feeling.
