Comment(by azaozz):

 Having a default value is a 'convenience' for APIs that store and retrieve
 something. It usually saves one conditional. Instead of doing:
 {{{
 $my_meta = get_post_meta($post_id, 'my_field', true);
 if ( empty($my_meta) )
   $my_meta = 'default-data';

 }}}
 we can do:
 {{{
 $my_meta = get_post_meta($post_id, 'my_field', true, 'default-data');
 }}}
