Mikel Maron: "Weblogs and Location". Mikel is a blogger I've known and liked for a while and I'm meeting for the first time at this conference. Mikel's work with maps and RSS is quite cool.
It's only when I was discussing with some other bloggers at lunch today that I remembered that I liked BlogTalk 1.0 because of the people you can hang out with, not only the presentations.
Jörg Kantel and Jon Hoem have both talked about video weblogs (vog).
A vog is a video blog where video in a blog must be more than video in a blog
Jon is envisioning a new kind of web tool which allows users to compose videos using bits and pieces of other videos which have been available under a CC license. They are using SMIL.
Stephan J. Schmidt delivered an interesting presentation on bottom-up knowledge management with weblogs and wikis. I must talk to him before the conference is over.
