What is the social network you use the most?

I ditched social media around 5 years ago, only spending time lurking and reading news sites (Reddit, HackerNews, Feedly) after that. With social media, I felt like there was too much noise and social comparison that contributed to feelings of loneliness and dissatisfaction. The rise of influencers and app-celebrities only furthered those feelings. It looks like I'm in the minority here! My lack of personal usage now makes it difficult to use social media for business purposes. I'm no longer familiar with what it means to "engage online". I'm actively trying to turn that around, but it's difficult to be in a "social media mindset".
