I’ve seen this on other people’s sites but didn’t really “get it” for a while–now I think I understand it: you can subscribe to this blog via facebook using the Networked Blogs application.
Does anyone know more about it than that? Does it make it possible for people to follow the blog without “friending” me on facebook?

I don’t believe you have to be Facebook friends to follow a blog. I think it is a great tool for the large majority of people using Facebook who don’t use RSS readers.
cool thanks Brandon!
