Over the last few years, micro-blogging has spread to the masses and everyone from Barack Obama to the New York Times to Amazon has joined in the fun. Essentially (and according to my dear friend, Wikipedia),
Micro-blogging is a form of blogging that allows users to write brief text updates (usually less than 200 characters) and publish them, either to be viewed by anyone or by a restricted group which can be chosen by the user. These messages can be submitted by a variety of means, including text messaging, instant messaging, email, MP3 or the web.
Some of the most popular independent micro-blogging services are Twitter, Jaiku, Tumblr, and Pownce. But even existing platforms like Facebook and MySpace have begun building in various types of micro-blogging functionality.
