Twitter..?
WTF is the point of it, I can’t really see it? Wikipedia’s take on it is:
Twitter is a free social networking and micro-blogging service that allows users to send “updates” (or “tweets”; text-based posts, up to 140 characters long) to the Twitter website, via short message service (e.g. on a cell phone), instant messaging, or a third-party application such as Twitterrific or Facebook.
It seems to be essentially pointless and more than a little lazy - I know people who are going mad over it and update themselves every ten minutes.. probably going to go the same way as myspace and Facebook and fade away.
