Technorati

The search for blogs. Really a great site as what is provided within one's own blogging program for searching is limited. This really has excellent possbilities for discovery. As for searching for library 2.0 in posts, in tags and in the blog directory, I'd compare looking in posts and tags to keyword and subject searching. There is the potential for locating items that possess "aboutness" of the topic matter when searching through the tags. Searching through posts is like a keyword search where it looks everywhere, actually more like a full text search, but same concept. Additionally, the blog directory seemed to have a comparable number of items as the tag search.
