There are some people who have no use whatsoever for the "blogosphere," but for others, it's a whole other way to find useful information. The BlogScope site
is an analysis and visualization tool for [the] blogosphere which is being developed as part of a research project at the University of Toronto. It is currently tracking over 36.94 million blogs with 840.79 million posts. BlogScope can assist the user in discovering interesting information from these millions of blogs via a set of numerous unique features including popularity curves, identification of information bursts, related terms, and geographical search.
Try putting in a search term for some topic you are working on, or, even better, put in your name, and see what you find.
I think you'll find it's an interesting site.
