In the Facebook Fan Box appears on your site, it usually shows your fans randomly or if you’re logged in, you can recognize that your friends who became fan of your page will appear on that box.
If you would like to know Who are the latest people liked your Fan Page, I’ll show you 2 ways to get that list.
These tricky are very easy and absolutely not new but they make me very interest. 
1. In your Facebook Fan Page
Go to your Fan Page, ex: http://www.facebook.com/4.Rapid.Development and make sure you’re an administrator of the page.
Facebook Fan Page People Like This Link
There should have a link: “people like this” with the current total Fan of your Page above, click on that link.
Facebook Fan List Pop up
A pop up will come out with the list of your fans and latest people will appear on the top.
2. Trick a Facebook URL with your Fan Page ID Number
Also, you’re required to log in with an admin account to get the list. Simply open a link below and replace my Fan Page ID Number (192737727433644) with yours:
http://www.facebook.com/browse/?type=page_fans&page_id=192737727433644¬if_t=page_new_likes
Facebook Fan Page Latest People
Note: if you set a custom name for your Facebook Fan Page, you have to find your Facebook fan page ID Number again in order to do the tricky.
