Like people already wrote, FB is not used anymore to share your vacation and see your friends food plates. Me and about everybody around me are using FB for Marketplace (big here, about the only platform used to buy/sell), and for all kind of groups, being for hobbies like RC cars, Astronomy, Funko Pop, RVing, Painting, Costco, whatever, etc.

I have not posted a pic or a thought on FB for years, nor really read something from my hundred friends there in my FB feed, but I go there about everyday to browse my groups.

It’s not as good as old forums about your car brand/model etc, but it is happening there now.

If you want to replace FB for friends/family/picture/events, no clue, maybe IG lol

it was mostly flame wars, alt.bin.pictures.erotica, warez, discussion about The Simpson, and of course The Oracle, and Kibo.

EDIT for young people, the usenet oracle and kibology

Linux is C only, ever read the rant by Linus last century about C++ ? I was there, in usenet
