There may have been few things that protesters, politicians and activists share, but during the G20 meeting, they were united by their use of Twitter.
The micro-blogging service was heavily used by all those involved with the meeting, be they in the debating chamber, quizzing politicians after briefings, or protesting beyond the police cordon.
Social media was in use prior to the event too. The Metropolitan Police analysed activity on websites such as Facebook, MySpace and many others to see how many were likely to join the call for protests at the G20.
Plans for how many policemen and woman should be put on the streets during the G20 were drawn up with regard to this analysis.
