BlogPulse profiles are now online as a beta feature. The new tool from Intelliseek displays various information Intelliseek collects about a the top 10,000 blog URLs such as people linking to the blog, sites linked by the blog, most recent blog posts, and common keywords. They also provide a list of 10 blogs that cite similar links and text.
My favorite feature is the common keywords identified in recent posts. It would be fun to take a group of keywords and guess the blogger.
