Today's word is twitterati, thank you Chris Rusbridge. The word appears in a post on 11 March by Chris to the JISC repositories list. He is the Director, Digital Curation Centre, at the University of Edinburgh.
The meaning of the word is very clear - twitterati are people who know about and presumably use the Twitter software and the term is pretty well established and widely used. In fact there is a whole world of language which derives from the twittering habits and preferences of many people - Twitter, says Twitter, is "a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?"
In the course of checking out twitterati, I also came across TweetMinster, "a place where real life and politics tweet." It seems to foster twittering amongst the parliamentary twitterati at Westminster. Do we want our Australian members of Parliament doing this kind of thing?
Twitter is not a term confined to people with curious tastes in communication. Go to twitternet or for that matter email the firstname.lastname@example.org and you will encounter something completely different.
