 * I see the following error using this plugin in my development environment:
 * `Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback,
   non-static method WPCOM_Liveblog::add_rewrite_rules() should not be called statically
   in /srv/www/christiaanconover/wp-includes/plugin.php on line 505`
