How can I remove the title “leave a reply” in the comment box in twentyeleven?

1. You can filter the default comment_form arguments (which is what’s causing the “leave a reply”).

   Just drop this in functions.php or in a plugin file. It would probably be better to put it in a plugin and keep your twenty eleven theme unedited (read: easily updated).

   <?php
   add_filter( 'comment_form_defaults', 'wpse33039_form_defaults' );
   function wpse33039_form_defaults( $defaults )
   {
       $defaults['title_reply'] = '';
       return $defaults;
   }

2. edit comments.php,
   and find:
   comment_form();

   edit to:
   comment_form(array('title_reply'=>''))
