Currently, there is a large number of communication channels, and of different types, made available to technology users. Some of these communication channels are of the “store-and-forward” type, in the sense that the information is delivered in one direction, and remains accessible (almost) indefinitely for the remote parts to view it when he has the time; e-mail is the grand-daddy of this communication style. Others, however, are more immediate, and require rapid response (often interrupting other tasks); telephony is the obvious largest contender in this category.
Each of these different communication channels typically requires its own “app” to access the information being exchanged. As the number of channels we need to give attention to increases, the harder it becomes to manage them all efficiently.
