Weird one to me is Facebook use. Why hasn't it dropped off with anyone under 50 or especially under 30. Haven't heard of any in the younger set using it in years, or rather, dominance of the other key platforms in that group.
I think this vague term of 'use' isn't being very helpful here. Does that mean actively posting original content? Commenting? Liking? Sharing? Just scrolling/reading? Seems all those modes have a much different involvement, and likely quite different measures.
I don't use FB myself (in any mode), so this is second-hand... but my younger friends (< 30) use FB only as a necessary, lowest-common-denominator tool to keep in touch with less-close family/friends. It's low-effort ambient connection, not passionate interest or obsession. (I'm in a rural area with fairly low online/tech interest, which might affect things too.)
