'The Web at 20' launch of Digital Revolution was classic swimming duck event management - calm and smooth to all above and frantic paddling underneath and behind the scenes. Dan Gluckman and I spent the morning editing video, uploading blogs and making sure tech and wifi were working on the day.

I spent the whole of Friday 10 July 2009 supressing the urge to punch the air in excitement at the site's launch and the subsequent chance to meet, not only Tim Berners-Lee, but Bill Thompson and Baroness Greenfield - and to see them talking about the very subject I have made my life for the last few years, and for years to come.

Sir Tim was excellent; I doubt there was a person in the room that didn't feel a degree of awe in his presence, and his self effacing answer to the reported question by a customs official who asked why he'd invented the web was lovely: "Well, somebody had to." A very British genius.

Small miracles allowed us to successfully live-link to San Francisco to see and hear Chris Anderson describe his ideas around the 'free-conomy'. Baroness Greenfield was energising and challenging to the web-fans in the room, and Bill Thompson delivered a wonderfully humane brand of geek wisdom.

An outstanding launch to a unique project about an immense subject. I hope that our open source production can carry the momentum of this debate forward, and that the web communities, creators and users will join us to make the best documentary possible worthy of the web.
