You say that like it's a bad thing? :-) I almost never see posts on facebook from my actual friends. it's all either E.D. adverts or bots pushing an agenda.
I do not say it like it's a good thing or a bad thing. I'm just observing this fact.
I'm not in that very small and specific set of people but I am not that far from it; last week I logged into Furrymuck for the first time in decades and attended a memorial service for one of its wizzes and remembering how that text-only MMORPG worked sure was interesting when I wasn't busy crying my face off.
