How do I get my site name next to the main site like button, instead of 'this'?

Yet another silly facebook "like" button question. We have a main like button for our website, which is basically the like button with text to its right resembling "x,x,x and xx others like 开发者_开发问答this."

What I want is to change the text to "x,x,x and xx others like Example", where Example is the name of the site.

I have included the six Open Graph meta tags, and the like button is generated by the following FBML:

<fb:like href="http://example.com/" layout="standard" show_faces="yes"></fb:like> 

What am I missing or doing wrong?

Try adding...

<meta property="og:site_name" content="Your Site" />

...in your head element. :)
