Facebook Like Button not doing anything??

Hello,

I have recently been introduced to this new "Facebook Like Button" thing, and I'm having an issue.

According to the websites I've visited on the subject, you can put this "Like" button on ANY web page (not just Facebook) and you can specify ANY URL (not just Facebook URLs) as the subject of the "Like" button.
Supposedly, when a user clicks on this "Like" button on your web page, if they are signed into facebook, your web page will show up on their Facebook page somewhere?  Is this true? Becuase my friends have been clicking on my like button and my website is NOWHERE on their facebook pages.  Where is this supposed to actually show up and help my marketing?

I am attaching the code I've used to embed this page, and you can see the link live at

Please try it for yourself.  Can anyone tell me why it's not doing anything?

Thank you for your help.
