For those of you who have websites that suggest visitors “become a fan” of your Facebook page, you need to update your sites. Facebook has changed “Fans” to “Liking” a page.  At their annual f8 Developer Conference, Facebook announced platform updates that work to integrate their platform with sites across the web.

Now with more than 400 million people using Facebook and $100 million of them using Facebook from their mobile phones, Facebook wants to continue this growing trend and develop social applications that integrate web sites with their new tools.
