As students beginning working on their fourth essay, they are looking around for a blog to observe and participate on for a week. Finding blogs isn't hard, you just have to know where to look.
Technorati.com has a
blog directory that provides a comprehensive index of blogs by topic.
It also offers an "
authority" and a rank. The authority number is the number of inlinks to a blog (that is, the number of links from other blogs to the blog you are reading). The rank is calculated based on your authority rating. The higher the authority the closer the blog is to the top and the smaller the rank. So, a rank of "1" is a top-authority blog, if you will.
Technorati's front page also provides headlines of "rising stories" in the blogosphere that are interesting to peruse in their own right.
Another useful source for finding blogs is
Google's blog search. In addition to being able to search the blogs indexed by Google, it also provides on its front page top stories on the blogs or on Web pages that are inlinked from other blogs.
