Not that it applies to this blog at all but Web 2.0: Buzz-Monitoring and Tracking is a nice write-up of some solutions and I need to look at it more closely.

I've been trying to use Google notebook to track things but it's not working so well for me. The interface is kind of clumsy. Need to get back and try it some more, I guess. In the meantime, I can use the blog to call attention to articles that are useful for me and for my hordes of readers.
