1. insanely low-effort to post 2. requires NO discernment, proof, credibility, or peer review to post 3. 'viral' in that opinions circulate because other people have interacted with them, not because they are right or meaningful. so bad news, good news, real news and fake news all travel at the same speed, lowering discernment even further 4. echo chambers are baked into the form. people are more likely to interact with content they agree with vs. content that is true or impactful. this creates circles of people agreeing with each other on increasingly niched-down topics.
it is extremely different from newspapers and television.
