There is a new great-cool-useful-wonderful-powerful tool from Technorati: Tags. Maybe you heard about it on some blogs that wrote about it. The Technorati tags are from Flickr, Del.icio.us and blog posts. You can contribute:
– If your blog software supports categories and RSS/Atom (like Movable Type, WordPress, TypePad, Blogware, Radio), just use the included category system and make sure you’re publishing RSS/Atom and we’ll automatically include your posts! Your categories will be read as tags.
– If your blog software does not support those things, don’t worry, you can still play. To add your post to a Technorati Tag page, all you have to do is “tag” your post by including a special link.
And there is a bookmarklet that lets you add tags to a post in much the same way you do with flickr and del.icio.us – you just write the tags in a text box, separated by spaces. Matt did it to help us. (via Boing Boing)
Update: there are more two good articles – Technorati Takes Tags Global and Technorati tags: Take 2.
