Facebook shares features with any page on the Web

The Facebook "Open Graph API" is one more way for Facebook to become the leader in all things social. Estimated roll out for Q2 2010.

The Open Graph API will allow any page on the Web to have all the features of a Facebook Page. Once implemented, developers can include a number of Facebook Widgets, like the Fan Box, or leverage any API, which enable the transformation of any Web page so it functions similar to a Facebook Page.

For example, AwesomeTees might decide that strategically they would like to locate their brand identity at www.awesometees.com. AwesomeTees will install the Fan Box widget, which will allow any Facebook user to "Become a Fan" of AwesomeTees, thereby establishing an official connection to AwesomeTees. The user will then have AwesomeTees listed in their list of connections on their profile as Pages are represented today. Additionally, any content that AwesomeTees publishes on AwesomeTees.com will show up in the stream on Facebook like it normally would. And, any time the user searches on Facebook, AwesomeTees will show up in the typeaheads and prominently in search results.
