People's identity on the internet almost become as important as theirs in real life. People just each other by what they see on each other's social media profile. Our posts certainly represent who we are, what we think and what we care. But it is absurd and superficial to weigh it too much. Cyber identity is not the full us. Also, although real-name policy protects our internet environment because peopole care about branding their identity online, but the fact shows real-name policy could hurt people by sharing their information in public.
