The G20 summit provoked a day of forceful protests across the city, with protesters rioting around Threadneedle Street this afternoon. t5m Insider went down to investigate at Trafalgar Square, but all we came across was a quiet and sunny peaceful protest. We’ve been following the action from the office, and tracking the events on various news websites. The day’s events have been tracked second by second on blogs and live feeds. It was a day of cyber-reporting – The Huffington Post had invited citizen journalists to send in photographs from all over London, and Twitter has been blowing up with riot-related tweets.

Kate Day blogged on the that the protests have become a turning point for following news on Twitter.

‘All the world’s atwitter. Or so it has seemed over the last few months anyway. But with the G20, finally Twitter has shifted from being the story to becoming a tool with which to tell the story. As the G20 protests spread through the City, Twitter is finally being widely recognised as a great way to follow events as they unfold. The Telegraph and are collating their journalists’ tweets, as is Sky News. Yesterday, Reuters hosted a live discussion with Robert Zoellick, the President of the World Bank, in which he answered questions from Twitter. Most mainstream media organisations have reporters tweeting about the summit.’

‘And of course you can follow tweets pouring in about the G20 at Twitter Search. Next month, the impact of Twitter and microjournalism on newsgathering will be examined at media140, an event which will bring together bloggers, journalists and publishers’.

Kate suspects that the G20 will stand out as ‘a turning point for Twitter, and indeed social media more generally, and its relationship with journalism’.
