Looks like the IndieAuth Client for PHP dropped the `me` param when it exchanged `getAccessToken()` for `exchangeAuthorizationCode()` around when it moved to the 1.0.0 version, and that WordPress’s IndieAuth plugin never fully caught up, I’m thinking because Aperture hadn’t upgraded till now (and no one is foolish enough to self-host it, let alone the very latest version). (Also, please correct me if I’m wrong.)
