• The average age seems to be much higher. I joined when I was 16 and feel quite young unlike on other social media.

Enjoy. Less echo bubbles. This goes in both directions, but mainly I value that younger people are able to be part of "mature conversations". Don't get me wrong, I don't mean to underestimate your worldview or anything. It's just that I'm remembering when I was around your age, the Internet was in a raw form, and it felt much like this. I was amazed to be able to talk with other adults and learn about their tastes on say books or movies when I joined some theme specific chat channel (via protocol IRC). At some point this changed drastically (e.g. Facebook connecting people from real life/ schools).. and I think nowadays TikTok, Insta, and for the most part, even YouTube are just centered around being young, pretty... very much like mainstream TV.
