How to track facebook shares

Question

I have the following code to allow people to share a link on their facebook

<div class="fb_share">
    <a name="fb_share" type="button" share_url="http://www.handybook.com"
        href="http://www.facebook.com/sharer.php">Share us on Facebook</a>
    <script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share"
        type="text/javascript"></script>
</div>

How can I track whether someone actually shared the link after they shared the link? thanks!

You may choose to incorporate Gigya to facilitate and track sharing, not only on FB but across other social networks, too.

I've worked on projects where this served the purpose well.
