In the five months since Technorati introduced the idea of tagging and indexing blog posts, more than a 14 million blog-posts have been tagged, with more than one million distinct tags in use.
This weekend, Technorati reached another milestone, our millionth indexed tag. It amazes me that since we launched our service to track tags on blog posts on January 17th of this year, there has been an explosion in the use and understanding of tags. Here's a recent AP article on tags, if you're new to the phenomenon.
Beyond a million distinct tags, there's also a lot of bloggers tagging posts. At the moment of the 1 millionth blog, we had tracked 14.2 Million tagged blog posts. 14.2 Million tagged posts in just over 4 months, that's a lot of posts.
