In my dConstruct post the other day, I said

James Bridle was the highlight for me I think. He spoke about the history of the internet, not how it started, but how data evolved. He talked about GeoCities, and how much of that information is lost, the internet archive wayback machine has some of it, but not all. The whole of the internet archive fits into a shipping container. It's a special Sun data center one but it's still a shipping container. He taught me about wiki racing and introduced me to Wiki Hunt which I think is a genius idea. And finally, he told us about the history of edits on wikipedia. He chose the Iraq War page and collected every edit and revision ever made. And then printed it. It ended up being 12 volumes of fairly large books. Leafing through it, which Alex and I did during the break, shows trolling edits, and informative edits. Amazing and beautiful. Amazing to think that there are 12 volumes of history for one article, and yet as a child I remember having a set of encyclopaedia which were probably of a similar size, which were covering every subject in the world.

When reading Jeremy's dConstruct review I noticed he'd linked to James's own article On Wikipedia, Cultural Patrimony, and Historiography, so I went off and took a look and I'd thoroughly recommend a read of it.  It'll give you a far better insight into his talk, than my paragraph could.  Or alternatively you could listen to the audio, whilst looking at the slides
