Searching the World Live Web
Live Web search got a lot bigger yesterday, when Google launched its new blogsearch engine. There's no direct link on the Google index page yet. For now, you can find it in the roster of services behind the "more" link. There are 29 of those, and Blog Search is the newest.
But the news is still big. It legitimizes the Live Web--and blogging in particular--in a big way.
Far as I know, the blog search category was born when David Sifry put a hack he called Technorati on a Penguin Computing Linux box that lived in his basement while he and I were working on "Building With Blogs", a feature for the February 2003 issue of Linux Journal. Dave needed to research blogs, so he created a tool for it. As of today, Technorati's traffic is #751 on Alexa, pushing 80 million page views per day (Disclosure: I'm on Technorati's Advisory Board.)
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.
