Google API Relation Browsing Outliner
Since a few people in my blog neighborhood have a knack for both Google and outliners, I figured I should post this. It came out last spring, so you may already know about it. GARBO
"lets you enter a URL, and uses the Google API to search Google for pages that are either related to (using the related: keyword) or linked to (using the link: keyword) that URL. You can then click on the triangle next to any of the results to find pages that are related or linked to those results, and so forth and so on."
Enter your blog's URL and then click away at those triangles!
