Facebook made some changes yesterday to the way pages work. They introduced "community pages" and changed some terms that you might need to change on your website as well. If your website says, "Become a Fan on Facebook" you might see how things go over the next couple of weeks and be prepared to change it to a term that matches facebook's nomenclature. You can see below that they have changed it to "like" instead.
Here is the faq section from facebook's home page on these two topics.
You can see the entire Help Center on Facebook Pages if the following doesn't provide your answer.

Community Pages are a new type of Page that enable you to see what people are saying about the things that matter to you, and discover the friends and people who share these connections with you. They are similar to any other Page to which you can connect, although they won’t generate stories in your News Feed, and won’t be maintained by a single author. Where available, they also show Wikipedia content for the relevant topic, which Facebook has licensed under the creative commons license.
We think your experience on Facebook will improve as your profile is turned into a living map of all the connections that matter to you, instead of a static list of your interests.

Community Pages are built around topics, causes or experiences. Official Pages are maintained by authorized representatives of a business, brand, celebrity, or organization, and they can create and share content about the entities that they represent. Community Pages, on the other hand, won’t generate stories in your News Feed, and won’t be maintained by a single author.
While Groups allow you to communicate directly with other people on Facebook about a specific subject, Community Pages simply enable you to learn more about and see what others are saying about additional topics that interest you.

No. When available, we update the information and profile picture based on the article for that topic in Wikipedia. At this time, there is no way for people who choose to connect with a Community Page to add their own pictures or edit the information.

Community Pages have slightly different content than official Pages. When available, they display a primary picture straight from the Wikipedia page of that topic, along with an info section also from Wikipedia. Related posts from other people on Facebook will also be displayed in real time.
However, since Community Pages are another type of Page, we don't differentiate between them when listed on your profile or in search results.

Community Pages are meant to be the best collection of shared knowledge on topics that interest you. Where available, they show Wikipedia content for the relevant topic, which Facebook has licensed under the creative commons license.
If we can’t find the right article from Wikipedia, we might be asking for help from the community. You may see messaging on these Community Pages inviting you to make these Pages more useful and interesting by signing up to contribute in the future or by suggesting a Wikipedia article.

To improve your experience and promote consistency across the site, we've changed the language for Pages from "Fan" to "Like." We believe this change offers you a more light-weight and standard way to connect with people, things and topics in which you are interested.

When you click "Like" on a Page, you are making a connection to that Page. The Page will be displayed in your profile, and in turn, you will be displayed on the Page as a person who likes that Page. The Page will also be able to post content into your News Feed.

Can I still "Like" a News Feed story about my friends Liking Pages?

No. When you see a Feed story about a friend Liking a Page, there will be no feedback links below that story. However, if you hover over the Page name, you will see a small preview of the Page and the number of other people who have also Liked that Page. You can then Like that Page to add it to your profile, or you can click through to the Page itself.

Yes. Liking a Page means you are connecting to that Page. When you connect to a Page, it will appear in your profile and you will appear on the Page as a person who likes that Page. The Page will also be able to post content into your News Feed.
On the other hand, when you click "Like" on a piece of content that a friend posts, you are simply letting your friend know that you like it without leaving a comment.
