Twitter is an online service, which revolves around the question “what are you doing?”. Users may post short topics (known as tweets), under 140 characters in length usually with such messages as “leaving work” or “eating a pie” etc, although many are more interesting than that.

Using the twitter service, users can also “follow” other Twitterers to keep updated with their recent activities.

In short, it behaves partly like a scaled down blog and rss reader.

in addition, because of the small size of the tweets, it is possible to recieve sms updates through your mobile phone to follow your friends.
