Who even uses Facebook anymore? I don't know anyone who posts to their own profile anymore, and I'm part of the generation where literally everybody was posting every detail of their lives to FB as students.

For "seeing what old friends are up to", that's entirely shifted to IG. (Yes, pedants, I know that this is an FB product.)

The only time I ever open FB nowadays is for the marketplace, and when I do, all I see in the feed is garbage brainrot from big slop accounts.
