Facebook today launched its latest missile in the war against Google for the trophy of world wide web domination. At F8, the companys developer conference, in San Francisco, CEO Mark Zuckerberg introduced the companys Open Graph, which essentially extends Facebooks like feature to a multitude of external web sites, allowing users to feed their activity back into their Facebook news feeds. It also gives brands and site owners the ability to better track demographic data of the users visiting their sites. With this feature, Facebook has made a huge move in driving forward the semantic Web something that Google failed to do with Buzz.

Facebook has won the Internet, said Damon Cortesi, CTO and co-founder of Untitled Startup. Facebook has always been social, but in terms of dominating the Web over Google they have made strides today.

Thus far, companies such as Yelp, Pandora, CNN.com and countless others have installed the like feature. Levis has even built a dedicated Levis Friends Store that includes like options for all of its items. When a person likes a Levis item, or even recommends a CNN story, it not only shows up on the users Facebook profile, but on the brand or news web page itself. Moreover, if a Facebook user has already liked the item, his or her friends will see that when they visit the external site.

Apparently it takes all of 10 minutes for a Web site owner to implement the Open Graph feature into its digital presence.

The ease by which you can now integrate Facebook onto your site is a ridiculously simple proposition to any web site owner, Cortesi said. For one, it doesnt take long, and two, you now have the worlds largest social network talking about you. Why wouldnt you do this?

Brands who implement the like feature and play into the Open Graph can add a Facebook token to their Web sites that claims ownership of a page, and then can leverage Facebooks Insights, which is essentially a mini Google analytics. They can then get demographic data, such as gender and age breakdowns, as well as frequency of shared pages.

This type of data for marketers is huge, Cortesi said.

While a step forward, users cannot forget the privacy implications of this type of feature. Privacy still remains the unknown black hole of the semantic web, and the ability for brands to make Facebook integration even easier will create an explosion of Facebook inclusion on web sites. This could lead many users even further down the path of allowing themselves to be potentially profiled.
