I have been looking at Technorati tags a bit and started to add them to some of my blog posts. In the process I noticed the varying number of posts that have received these tags so I started to keep track. I included knowledge management and km in the list even though they are not really a 2.0 topic, the new approaches to km do include enterprise 2.0. These do serve a rough measure of awareness and popularity of these topics. I wondered how they compare with Google search results so I did several comparisons. The Technorati tags are first. Then the Google searches (in parentheses) are provided.

The Technorati tags are measure of blog content supply (by people who use tags - generally more technically advanced bloggers) and the Google searches are a measure of content supply across all web channels, including vendor sites. You can see that they do not always correlate. One of the biggest contrasts was enterprise wikis vs, business wikis. I assume part of this is because the software suppliers prefer the enterprise wiki label. I placed the links to each tag at the end of this post.
