I have a confession to make. I'm a Twitter junkie. As soon as I say that people know what I mean. The word, 'junkie' is an evocative word, that paints a picture of compulsive behaviour that interferes with other facets of the 'sufferers' life. This is why journalists use the word junkie. It provokes and paints a picture with a single word. When used to describe people who inject drugs, the 'j' word presents a two dimensional cartoon. An image of an emaciated person prepared to rob his or her mother to get their 'fix'. It is stereotyping of the worst type. Fortunately I am not the only person to think so.
