Dave Sifry's at it again with another cool way to look at the web. Technorati now features tags. Tags at technorati are the same concept as tags at Del.icio.us--informal categories that you make up on the fly. Technorati will automatically make tagged entries from the categories on your blog, or you can add this to your pages to make your own:
<a href="http://technorati.com/tag/[tagname]" rel="tag">[tagname]</a>
Here are a few well populated tags at Technorati right now:
Technorati augments its material with links for the same tag at Del.icio.us and Flickr.
