Only load the user tags when arg(0)=='user' and $user->uid > 0

I noticed that when the user meta tags are enabled that it automatically tries loading all metatags for every user_load(), which happens on every page. Given that most pages don't need these metatags, it might be better to only load them when arg(0) == 'user' and $user->uid > 0, i.e. when the visitor is not anonymous. Thoughts? The code would change to the following:

function nodewords_user($op, &$edit, &$account, $category = NULL) {
  global $user;

  switch ($op) {
    case 'load':
      if (arg(0) == 'user' && $user->uid > 0 && variable_get('nodewords_enable_user_metatags', TRUE)) {
        $account->nodewords = nodewords_load_tags(NODEWORDS_TYPE_USER, $account->uid);
      }
      break;
