In this old (2005) post, Doc applauds the launch of Google Blog search, and comments on the relevance of that kind of search compared to the “non live web”.

As of today, Technorati’s traffic is #751 on Alexa, pushing 80 million page views per day.

Other Live Web search pioneers include Bloglines, Blogpulse, Feedster, IceRocket and PubSub. The results they yield are radically different from what you get with Wide Web searches, as well as from each other. Mostly, the results are newer. They’re also more likely to come from individuals and live news services than from companies with static sites.
