Weblogs as filtering tools

Why blogging isn’t a fad. Arnold Kling offers one of the best explanations I’ve seen of the value of blogging as a distributed information filtering mechanism.

“This filtering process makes all of us more efficient. Information with low value does not travel far. Information with high general value tends to travel the farthest. Information with low general value but high local value tends to reach interested people but then die out because as it gets passed along its value decays below the threshold. Everyone tends to receive information with a high value to them, and they avoid having to read information that has low value to them.”


Gradually working off the backlog of items lurking in my news aggregator. This is, indeed, an excellent explanation of the value of weblogs in organizational settings and in communities of practice. I might have gotten to it earlier, but it’s from another of those Corante blogs that continue to refuse to offer RSS feeds. I have yet to hear the argument about why RSS feeds are a bad thing from Corante’s point of view. But until I have time to scrape these blogs into my aggregator I just don’t have time to track them, no matter how excellent the content may be.
