Submirror wizard updates... commenting out Wordpress (not sure what to do with it), LinkedIn (can't find documentation on any public RSS/Atom feeds from it, it seems that a feed of your updates doesn't currently exist?), and StatusNet (we'd need to know what to do with it; could take webfinger-style addresses or such.) Also added a commented-out Facebook section; it seems that there may not be a current way to get at public updates via RSS/Atom either, or if it is it seems really inconsistent and undocumented. (You can get at your friends updates by jumping through some hoops, but it seems we'd want to mirror a single account's own update feed?)
