What is Micro-blogging ?

Micro-blogging is the practice of sending brief posts to a personal blog on a micro-blogging Web site, such as Twitter or Jaiku. Micro-posts can be made public on a Web site and/or distributed to a private group of subscribers. Subscribers can read micro-blog posts online or request that updates be delivered in real time to their desktop as an instant message or sent to a mobile device as an SMS text message.

A new idea for Micro blogging has been to turn it into a way to talk to other people about work. It allows a person to give quick news or information to the people they work without sending a lot of emails and without the spam they get in their email account. New companies such as Yammer have been started who want to help allow workers to talk to each other with about work and share what they need.
