Time, History and the Internet - barcamplondon2

Last weekend I gave a talk at BarcampLondon2, entitled "Time, History and the Internet". I covered a range of issues about how we are living in a very forward looking culture and how this makes understanding the past more difficult. I feel that this is a problem and one that is only going to increase as more and more of our content goes online.
I've slightly extended the presentation and written fuller notes to go with the slides. They are a 15.5MB pdf file Time, History and the Internet. Some people asked to see the slides and some people wanted an MP3, sadly I didn't get round to recording the talk, but the notes should help. I'd really welcome followups from people who heard or when you read the talk.
