For me Facebook is no longer relevant for friend stuff. But I find it pretty good in group stuff. For example their are groups about my town where I live. Historical groups or modern ones. Or a group about a specific car model I own. I just have to filter out all the ai / porn slop that goes into my feed.

> a group about a specific car model I own

This is basically the only reason why I occasionally log in to Facebook these days. Facebook groups seems to be the place where car owners gather to share information regarding their vehicles, at least here in Finland. I have found discussions in these groups very valuable e.g. when I'm diagnosing a problem or evaluating whether some defect will be covered by warranty or not.
