Just a quick note that the same principals I used a few weeks ago to add XFN support to Blogger’s Link List work just fine when applied to the new Blog List blogroll page element, available on Blogger in draft. I’ve just done this, so everyone in there should be computer-officially my friends the next time a crawler comes through and notices.
A quick note of warning, though: if you edit the template of a page element, then any changes that Blogger makes in the future to the default page element template won’t get applied to yours. So if things start acting weird or you’re not getting a new bug fix, you may have to copy in a “clean” version of the page element.
