The joys of commuting

Just when you thought that the January blues couldn't get much heavier...

On a more serious note, I have been thinking about something I read on Om (I think) around the flickrisation of Yahoo. At some point in the article there was a justaposition of concepts and approaches in the search world between "tagging" (Flickr, Delicious etc) and the "cold mathematical approach" of Pagerank.

I guess the big question is, are there enough taggers (are we all taggers?) to improve the accuracy of a Tagged search versus a Pagerank. Or.... is the web going to come alive?
