This is a valid point. I am not the poster you are responding to but the top level poster. I too don’t follow people I know and perhaps that’s the difference from the social platforms. In that regard it is more like YouTube, but unlike YouTube, the algorithm isn’t radicalizing me other than making me want to learn guitar again.

So what is it about YouTube that makes people more likely to become radical incels willing to shoot up a school, and TikTok makes people more like to learn a new dance routine and leave with a smile?
