Do you really want to be friends with 8 billion people? Let's say you want to be friends with only 500 of them. How should those 500 be selected out of people who see your tweets? It has become a norm in social media, only real-life friends follow you on social media if you are not a famous person, otherwise its a suspicious behaviour. People can have a transient meaningful conversation in the comments section, never to see each other again. My school teacher jokingly gave a small scenario, he said "Imagine you know everyone in the city, you have to say hi or atleast nod to everyone. Not doing it would be to acknowledge you don't care for them."
