#14 Technorati

I've had a look around Technorati using "learning 2.0" as the search term and it's interesting to compare the number of hits you get under blogs, tags and blog posts. Tags obviously narrows the field but there is still some superflous material getting through. Looking at the topics listed under search terms and tags and the most popular sites I wonder if technorati or similar search facilities could ever replace dewey and subject headings. I think at this stage the search results are still too broad and our current way of cataloguing does by and large yield a better hit rate. Who knows though what may happen in the future particularly with more and more people using on line catalogues.
