I see the wORDpRESS PR posse is out in full force with 5 downvotes and counting. Nice try. Too bad El Reg isn't Facebook nor a WP site integrated into the worldwide blogcommentardspace, so the vast majority of your fellow slacktivists seem to be absent. Not that it matters. Downvotes are a badge of honor.
Anyway, if you must run WP, this vuln is yet another reason to block /xml-rpc.php.
