From the horse's mouth

Chances are you have heard of Twitter. It started as single-line blogging service, to let you update your daily activities, by posting quick snippets. And it was a revolution to the internet in the same way as blogging was. Most include boring everyday happenings of common people, much like status in your favourite IM client, but this is really cool. Twitter is collecting all twitters which mention any of US presidential candidates on one page and stream literally flows. You can immediately read what thousands of people are saying about them instantaneously. I am much impressed by this use and to this day, I am amazed at the power of internet by some or other innovative use.
