線上身份和使用者名稱的演變
Did you know that the concept of a username dates back to the early Unix time-sharing systems of the late 1960s? Originally called "user IDs", these short strings of codes were strictly designed for resource tracking and security permissions. As local area networks grew into the worldwide web, systems like IRC (Internet Relay Chat) and AIM (AOL Instant Messenger) shifted the username from a mechanical code into a form of self-expression. Users began choosing screen names like CoolGamer99, laying the foundation for modern internet culture and digital branding.
