Don't actually remember when I read this the first time, but it would have been within a few months of publication. I was reminded of this again and decided I should add it here.
For context, I was reminded by this Techdirt article: www.techdirt.com/2022/11/28/contrary-to-popular-opinion-most-teens-get-real-value-out-of-social-media/
commenting on this pew research study: www.pewresearch.org/internet/2022/11/16/connection-creativity-and-drama-teen-life-on-social-media-in-2022/
At any rate, they reminded me of this book, which takes the novel approach of actually talking to teens about social media use (instead of assuming things).
It's remarkably straightforward and clear.
