Matt Brown is editor of Londonist.comOne of the capital's most-read blogs with over half a million visits per month. The site covers London news, events, food and drink and all the weird historical facets of the city that you don't really get anywhere else. Matt specialises in writing about London and has received recent commissions on the subject from Warner Bros. Pictures, Channel 4, Lastminute.com, The Guardian, Time Out and many others. He also helps run Nature Network, a social networking site for scientists...but that's another story.

Matt Churchill works with the Spooks at Edelman Digital in the UKWhen at work Matt plays on Twitter and comes up with cool things to do for Edelman clients. He consults brands to try and (hopefully!) help them understand the digital landscape that they operate in and to identify the opportunities that social media can bring to their business in order to help them provide a service that their customers will want to interact with. Matt is excited by the chance to help induce institutional change and make brands work better for their customers.
