Problem: Malcolm, Zoe, Kaylee, Simon, and River all work together on the same web development team. They are avid Twitter users and want a similar way to broadcast quick messages and updates to everyone on their team. Since these messages may contain confidential information, the team doesn't want them published to their public Twitter timelines or to any followers who are not part of the team. Solution: GroupTweet allows Malcolm and the gang to send messages via Twitter that are instantly broadcasted privately to only the team members.
