Abstract:

Twitter, often referred to as the water cooler of the Internet, teaches us the art of brevity by limiting communication to 140 characters or less. But unless you can compress instructional content in ingenious ways, you’ll find Twitter limiting as a method for delivering documentation. Instead, Twitter is better used for the following: eavesdropping on customer conversations; putting a personal face on your company; and increasing the reach of your announcements.
