Chris Lydon interviews David Sifry, father of Technorati. I like Technorati a lot – it is a very useful tool to track connections between weblogs (or the reading trails of the weblog authors).

David talks about this at the end of the interview: a hyperlink is a piece of metadata that created Google. Technorati now is adding another metadata element: time (when a hyperlink was created). With timed hyperlinks you can see how »attention votes« propagate through the web and who is influencing or inspiring to whom.
