Ask HN: What social media have you dropped out of?

I personally started by leaving Facebook in 2015, after I noticed feeling both anxious and empty at the same time when using it (the same happened with mobile notifications). I also heavily limit use of messaging apps and other platforms now. Then I started recording many conversations in podcast with no goal other than “let’s drop the bullshit mask for the public just talk like human beings”. I started actively making over passively consuming online media. But I feel like I still need a respectful and supporting online community, especially to share meaningful resources and links to grow as a person. I’m building a small one community centered around sincere and honest discussion, so I‘m wondering what other people who dropped out of social media miss online, what their experiences are, and what they feel could replace it in a healthy way.
