Why Did the Twitter People Decide on 140 Characters?

It’s pretty simple really:
Originally, Twitter had no character limit and several issues were aroused. For example, users tend to compose tweets of over 160 characters (the default SMS carrier limit). … They settled on 140, in order to leave room for the username and the colon in front of the message.
