I can see the benefit. It does not mean that you have not created your own personal echo chamber though.
I follow creators and folks on YouTube. YouTube then tries to create an echo chamber for me. It is very clear that the algorithm starts trying to show me more content like what I have already seen. I find it annoying.
These platforms, TiKTok, YouTube, Twitter, BlueSky etc are all going to do the same thing to some extent in order to maximize your time on the platform.
Other than YouTube, I just do not get into the follow culture and if I see news, then I will usually search out different platforms to see how the story is framed from multiple perspectives. I like to see the various biases whenever possible.
It's not that I do not understand the benefits that folks find from these experiences. I do.
People do create echo chambers for themselves and I still think that a lot of people delude themselves into thinking that are not part of one.
