Waypath is a new site that allows you to search for keywords in blog entries, find related blog entries and find sites linking to a blog entry. There are also several blogging tools (like the Buzz-o-meter) that look pretty spiffy.

Another cool site is Bloogz. You can use it to search blogs, see the most popular blogs and most popular searches.
