I mute people's posts and stories when their content is primarily rants, resharing some kind of social justice issue, resharing meme accounts, their children. So yeah I probably would not entertain a depressing couple’s spiral for more than a few 15 second clips. They know that too.
I’m only interested in the outgoing and interesting things, inspiration about locations or events, things that could include me. When these things really seem like they will never happen I typically remove them as followers and unfollow them. (Its much easier to curate your social graph as you go, instead of waking up one day and finding it too hard to fix your feed by attempting to unfollow lots of people)
I like to know people personally and I do that in person or over direct message
I only use the story for entertainment personally
Like someone else mentioned, I don't find many people’s online persona that interesting, and I have abruptly deactivated and/or deleted my own profiles before. Periodic curating has been good for me.
