Technorati

This is definitely a site that you can lose track of time exploring. No topic seems to be too small for blogging. In search for "learning 2.0" in Technorati, I discovered that there are more posts than blogs. "How many?" Well, the number changes constantly since people are adding to the content. The number also changes if you refine your sarch by the level of authority or the language that you want. One feature that is pretty neat for those who track usage is the chart that shows the content for 30 days of posts that have been tagged as "learning 2.0". Tagging is just the modern term for assigning subject headings or developing keyword access. Now everyone, not just librarians, can get into the act of classifying and cataloging data. It's pretty cool to give the power to the people who write the content.
