Instant messaging (IM)has become a popular way to communicate with clients and coworkers, and for good reason. Communicating over the Internet in real time can streamline communications and save you time and money. Plus, since most instant-messaging software is free, you don't need to invest more money in technology.

But before you rush into using instant messaging, think about whether it will really improve your business communications or just serve as another distraction. First, consider reasons to use an instant messenger:

Save on long distance. Using instant messaging to communicate with employees and clients in other parts of the world can reduce your long-distance phone bills. And most instant message services now also support voice conversations as well as video.

Conduct real-time interaction. When you work on a project with coworkers who have busy schedules or work in different offices, instant messaging facilitates quick and simple communication. Unlike e-mail, when you use an instant messenger you don't have to wait for messages to download from a mail server.

Reduce spam. Instant messengers get a lot fewer unwanted messages than e-mail.

Host chats and conferences. Public chat rooms are often chaotic, and it's difficult to conduct a focused conversation -- especially for business purposes. Although instant messengers are most commonly used for two-way conversations, most programs offer a conference or chat setting where your workgroup can meet.
