You might have noticed on the Kellysworld.net home page there is now a small grey box that has some personal message from me. That message is provided by Twitter, an interesting mixture of instant messaging, blogging and SMS. As other's can explain this cool service better than I, please see below for the Twitter description as provided by one of my favorite web sites, Wikipedia:
"Twitter is a free social networking and micro-blogging service that allows users to send "updates" (text-based posts, up to 140 characters long) via SMS, instant messaging, email, to the Twitter website, or an application such as Twitterrific. Twitter was founded in March 2006 by San Francisco start-up company Obvious Corp.
Updates are displayed on the user's profile page and also instantly delivered to other users who have signed up to receive them. The sender can restrict delivery to those in his or her circle of friends (delivery to everyone is the default). Users can receive updates via the Twitter website, instant messaging, SMS, RSS, email or through an application. For SMS, currently three gateway numbers are available: short codes for the USA and Canada and a UK number for international use. Several third parties offer posting and receiving updates via email.
Due to Twitter's success, a large number of sites imitating its concept have sprung up around the world, offering country-specific services (e.g. frazr) or combining the micro-blogging facilities with other ideas, such as filesharing(e.g. Pownce). In May, 2007, one source counted as many as 111 such "Twitter-lookalikes" internationally."
