Tuesday's Quote of the Day
"Though the account will be anonymous (ie, no named officials will be running it) it is helpful to define a hypothetical 'voice' so that tweets from multiple sources are presented in a consistent tone (including consistent use of pronouns)" - extract from the Cabinet Office's 20-page guide to writing a 140-character Twitter entry.
The guidelines for writing official "tweets" also says the tone should be "informal spoken English", and that government departments should not follow individual users uninvited, as this may be interpreted as "interfering 'Big Brother'-like behaviour".
