Surely reporting every boring thing is just mirroring real-life discourse. When people first started using social media, how they presented themselves was salient and selective because it was unusual to put everything out there in writing, and online personal profiles were being built up. Years later, social media has become the norm, and something someone wrote three years ago is long forgotten.
Everyone has listened to a friend, family member or colleague drone on about that nice food they had or about something boring their child did that they find riveting. I pose that it's just an easy way to do this while keeping the illusion that everyone else cares too. What has happened to ownership of our actions and intentions, private knowing of what we are doing and being, without an audience? I don't think this has ever existed in societies.
