It took one tweet on Monday evening as I left the office to light the virtual touchpaper. At five past nine I tapped: "Now Guardian prevented from reporting parliament for unreportable reasons. Did John Wilkes live in vain?"… By the time I got home, after stopping off for a meal with friends, the Twittersphere had gone into meltdown. Twitterers had sleuthed down Farrelly's question, published the relevant links and were now seriously on the case. By midday on Tuesday "Trafigura" was one of the most searched terms in Europe, helped along by re-tweets by Stephen Fry and his 830,000-odd followers. ... One or two legal experts uncovered the Parliamentary Papers Act 1840, wondering if that would help? Common #hashtags were quickly developed, making the material easily discoverable. By lunchtime – an hour before we were due in court – Trafigura threw in the towel. The textbook stuff – elaborate carrot, expensive stick – had been blown away by a newspaper together with the mass collaboration of total strangers on the web. Trafigura thought it was buying silence. A combination of old media – the Guardian – and new – Twitter – turned attempted obscurity into mass notoriety.
