Blogdex and Metalinker
I finally figured out how to put the Blogdex to use. It's a little tool called Metalinker. I read about it in a book at Barnes and Noble yesterday afternoon. There were two items in the whole book that interested me, this being one of them - this seems typical of any web design book I pick up these days.
Basically, you add some script to your page, and noodle with some configuration stuff, and presto! Every link on your site gets a little footnote that links to the Blogdex. You'll note that on Asymptomatic (the site you're reading), the footnote is a small superscript R. When you click the R, a list of other blogs appears that also talk about the linked-to subject. Pretty cool, eh? Maybe I should add a feature like this to PageCat.
