Because that way people don't find out their true identity- its their choice really...I don't use my real name.

Reply:They have very little creativity or they're like most people are these days: lazy.
Reply:Because remaining anonymous is safer. They didn't join to confess anything with their name and picture beside them. They think they can have more fun on Answers and can be more truthful in chat groups if they feel personally safe. The Internet is dangerous and they know that. Each is protecting their ego so they can run away if they get scared.

Reply:What makes you think they are hiding? Even if they are, it's a personal choice. I have to wonder why you care. You can easily add them to your buddy list, unless you are stalking or behaving in an otherwise unacceptable manner. Did I answer my own question?
