While I like Dave's blog, he is more enjoyable speaking. In this way, he is very much like Ted Turner, founder of CNN. So I immediately looked at CSPAN's stream of Technology Politics Summit on Politics & the Internet (it starts 55 minutes in). If you want see people's comments, check Dave's blog post.
My review: it is a wonderful explanation of blogging to Democratic marketers. And he did not talk to my lizard brain. ( Also, the two preceeding talks on liberal radio vrs right wing radio was very informative.)
