function _tracker_add($nid, $uid, $changed) {
  $node = db_query('SELECT nid, status, uid, changed FROM {node} WHERE nid = :nid', array(':nid' => $nid))->fetchObject();

  // Adding a comment can only increase the changed timestamp, so our
  // calculation here is simple.
  $changed = max($node->changed, $changed);

  // Update the node-level data.
  db_merge('tracker_node')
    ->key(array('nid' => $nid))
    ->fields(array(
      'changed' => $changed,
      'published' => $node->status,
    ))
    ->execute();

  // Create or update the user-level data, first for the user posting.
  db_merge('tracker_user')
    ->key(array(
      'nid' => $nid,
      'uid' => $uid,
    ))
    ->fields(array(
      'changed' => $changed,
      'published' => $node->status,
    ))
    ->execute();
  // Update the times for all the other users tracking the post.
