I love this clip. I found whilst I was study the history of the book as part of my library degree. I think it is a  very appropriate subject for the learning 2.0.

As for the rest of Youtube - i am not an avid viewer of the site but I am amazed at what it uploaded everday. There are some truely clever and talented people out there as well a lot of idiots (Jackass Videos etc. - need I say more).

I think YouTube, because of its popularity is a great and realtively cheap promotional tool. Many large corporation use it to promote their products as a means of attracting a younger audience e.g. Heiniken etc.

I see it  being used in libraries to promote facilites, and events but also as a way of advertising the value of libraries in the community. I have also seen libraries use YouTube for instructional purposes - as a how to ... both for staff and the public.
