Do you have to use your real name on Twitter?

[gutter]

Twitter isn't like Facebook. Facebook is all about connecting with people you know and having a network (like a really, really big family) of everyone that you associate with. Twitter is about following specific people that you're interested in. When you sign up for Twitter, there's no reason not to use your real name where it asks for it, but you want your USERNAME to be something different. Some people use their real names as their usernames, but there's really no reason to especially if you're worried about people knowing that it's you.
