I like this overview. We do some of this in Demystifying the Web presentations.
I use different tools (blog,rss,google reader,listsenves) but the logic behind it is good. You let the network filter and clean the web for what is important to you. Small groups filter and discuss. (I let the indicaiton of discussion tell me something is interesting.) I focus my "filter value" on the networks issues.
I also like the technique at the end for Q&A. He turns to the video and then answers questions.
