Version 2.8 was written in response to a user request for the inclusion of XFN data in the blogroll links. XFN stands for “XHTML Friends Network”, and it’s a way site owners can specify what type of relationship they have (such as friend, co-worker, neighbor) with the people they’re linking to. The format is built into the WordPress link manager, but I never included it in Better Blogroll because I didn’t think people used it.
If you specify XFN data in the WordPress links manager, Better Blogroll will now display it. If you don’t use XFN, your links will look the same as they did before. Because “nofollow” and XFN both use the rel tag, setting links to “nofollow” in the plugin will override XFN data.
