Here is more akin to a forum (or gathering in a physical sense) than a community. I only know a few usernames and that's because I've heard of the person behind each. The only central theme behind all my interactions is finding a post interesting, then reply to a comment once I've got something to say. I'm not interested in any individual, only on the discussion. Social media wants you to care, and care about a lot of things that are mostly irrelevant to your life.
