I guess it’s finally time to admit that I won’t be coming back to developing this plugin. The builtin Facebook sharing in Aperture does 90% of what I need so the motivation just isn’t there. Plus, as far as I can tell Aperture hasn’t opened up a Faces API to automatically tag people, so the best thing to do is ask Apple’s Aperture team to continue to improve their code. I won’t remove it from the plugin from Facebook since that seems to remove all photos associated with it, but I would recommend uninstalling this and just using Aperture’s built-in feature. The uninstaller is located here.
