Sphere links

I added the Sphere plugin to my other weblog since they have one for self-hosted Wordpress sites. It creates a list of other blogs and sites which may be relevant to an individual blog post on your site. It doesn't take up much real estate and everything is automated, but I'll have to see how useful the links are. It seems geared towards politics since they give you an option to include liberal only or conservative only links as well as all kinds.
