If you're looking for photos from VON, check the tag VON07 on Flickr. I'm currently watching Scoble and Arrington talking about video on the web. Scoble says the trick to quickly editing web video is to, well, don't edit it. Problem solved.
Arrington doesn't think it's worth the time, or at least hasn't figured out why it's worth the time investment for him.
On SEO: both see building a strong brand and creating quality content is the primary way to drive traffic, leading to links, which leads to high search engine rankings.

It's getting heated. More later.
