Ron, I was surprised when both of my kids said they and their friends don't use FB any longer. The younger one ordered her top 3 sites as: 1. Tiktok 2. Twitter 3. Instagram
They both consider FB annoying and something "old people" use. Once your parents and some grandparents are using a tool, apparently it's time to move on.
Twitter and Instagram were on everyone's list. All under 32. FB came in 2nd on one list and 3rd on another. Sample of 6 so far.
