What is Twitter

Is Twitter a social networking site?

Twitter is difficult to understand for most people.

Twitter is seen as a microblog--- a podium to shout out issues and advocacies.

Back in the day, there was Internet Relay Chat where people gathered to converse in real-time. That too was a stream of conversation that was a precursor to the more private AIM and Yahoo Messenger. Twitter is today's Internet Relay Chat, very much a live and active stream of conversation.

Twitter can be a source of news. It is being branded as the newswire for the 21st century. Call it the nervous system of the Internet that tells us zeitgeist in a microcosm.
