Have you seen this beautiful video?
I first saw this on Nancy White's blog where I had an interesting little dialogue with her. I was bowled over when I watched the video by its elegance and simplicity. Then it occurred to me - What would I see with a screen reader? I should soon have the answer to that question as I have sent the link to a blind colleague but I suspect that the answer will be - Not much.
The video talks about separating form and content but doesn't as far as I can tell.
Images and video are enhancing sharing of ideas and arguments but perhaps not for everyone. Reflecting on Michael Wesch's ideas in the video, who is us?
He has started a blog about it so I'll go and ask him

Sent you his address off-site. Wesch belongs to a Google group on Open Access anthropology and has been quite forthcoming on the goals of his project.
I also blogged about a few things I noticed in the way the video was diffused.
