Blogdex has a function called “Blogsocial.” It shows the blogs you link to and are linked from; it’s also called the “Social Network Explorer.” You could effectively play “Six Degrees: The Blog Version” through this site. Here are a couple of my ideas: (This is a take off Ev’s ‘Someone Should Build This’ series)
– Create a page where two random bloggers can see if and how they are linked to each other with the information given by Blogdex’s social network explorer
– Make a dynamic visual representation of the interconnections of bloggers (example at www.theyrule.com) with the information given by Blogdex’s social network explorer
The first one would be a great idea to bring together the blogging community, if you could even call it a community anymore (I say “anymore” as if I was a part of it when it might have been considered a community). The second one . . . well . . . it would be nice for the egos of the well-liked blog authors. A lot of these blogs are nice blogs, but they’re not well-liked (right, Biff?).
