This is an interesting article on Twitter, [a WEB service which lets you post items of micro data about yourself to let your friends know what you are doing, as well as keep a track on what your friends are up to]. I have been tweeting on twitter for a while now (does that make me an early adopter????? probably not !!) and I still found this article very interesting. Although it is aimed at the Web Strategist there are some good summaries and concepts about why & how twitter should be used and where it could all be going.
