What is it? It’s a ranked list of blogs. By Tag. David Powazek calls it “a mini Top 100 for any topic you can imagine”.
How good is it? I think it has some problems. Tags are publisher created and so publishers will add a lot of them, and will have an incentive to push the envelope on what is considered an appropriate tag for their blog. I believe, for instance, that I could make TechCrunch a very popular cooking site simply by adding the tag “cooking” to the TechCrunch blog.
There are three ways tags are added. Technorati has already tagged “over 2 million blogs” according to Sifry, and that appears to be accurate. The other two way tags are added are via publisher tools (note the text below is tailored to add a “web2.0″ tag):
Technorati did do a pretty good job of selecting tags that describe Techcrunch, however. There are definitely some changes I’d make, but it’s a good start.
The Blog Finder is available as the third tab on Technorati.
At first glance, I actually think I prefer the Rojo approach in this case. Rojo’s lists use tags that readers have used to describe individual posts that a blog has published. See our profile update here for details. I do, however, believe that lists, if they are useful, must be subject based. This is an interesting experiment in solving this problem.
