Group text messaging serves a different function than Tiktok or YouTube - surely you know this?

Or are you referring to Facebook in this thread while strawmanning another user regarding it in another thread?

Do you realize your link points out that only 33% of teens use social media, down from 71% in 2015?

So what “function” does it serve being on YouTube and TikTok when you need to interact with your friends?

I don't really understand this question. TikTok allows you to post and view videos your friends can see. Beyond that, it's a form of creation.

YouTube contains lots of human knowledge, because that's where many creators have decided to post their videos. I can't choose an alternative.
