show title if one of post meta exist

Question

I prefer below way,

$fb = get_post_meta($post->ID, 'ecpt_facebookpage', true);
$twitter = get_post_meta($post->ID, 'ecpt_facebookpage', true);
//etc...

if($fb != "" || $twitter != "" || $instagram = ""){
    echo "Follow Us On";
    if($fb != ""){ ?>    
      <a target="_blank" href="http://www.facebook.com/<?php echo $fb; ?>">
      <img src="<?php bloginfo('template_url'); ?>/images2/service-fb.png" width="25px" height="33px" alt="" align="right">
      </a>
    <?php }
    // And so on.....
}
