On the topic of radicalisation and community via social media (and YouTube) there's a useful Twitter thread criticising some research that's had a lot of play (I didn't bold it):

A new paper has been making the rounds with the intriguing claim that YouTube has a de-radicalizing influence. arxiv.org/abs/1912.11211
Having read the paper, I wanted to call it wrong, but that would give the paper too much credit, because it is not even wrong. Let me explain.
Radicalization via YouTube, as widely understood, is when someone watches a few partisan videos and unwittingly starts a feedback loop in which the algorithm gradually recommends more and more extreme content and the viewer starts to believe more and more of it.
The key is that the user’s beliefs, preferences, and behavior shift over time, and the algorithm both learns and encourages this, nudging the user gradually. But this study didn’t analyze real users. So the crucial question becomes: what model of user behavior did they use?
The answer: they didn’t! They reached their sweeping conclusions by analyzing YouTube without logging in, based on sidebar recommendations for a sample of channels (not even the user’s home page because, again, there’s no user). Whatever they measured, it’s not radicalization.

This caught my attention because the family friend (upthread) mentioned that she'd heard that YouTube was creating communities, acceptance, and wasn't nudging young people towards extremes.
