As the G20 protests spread through the City, Twitter is finally being widely recognised as a great way to follow events as they unfold. Here at the Telegraph we are pulling tweets into our G20 page (with some help from Twitterfall). The Guardian is collating its journalists' tweets here as is Sky here. 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. It's been wonderful to sit here at my desk and follow all sorts of observations, pictures and videos coming from people in the heart of the throng in central London as well as from those watching from afar.

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. I will be going along and you can follow my tweets on my Twitter account. I suspect that the G20 will stand out as a turning point for Twitter, and indeed social media more generally, and its relationship with journalism. I hope this is just the beginning.

But here I am falling into the same trap as everyone else and making Twitter the story again. So I'm going to shut up now and get back to watching screens.
