Facebook Social Plugins tie you up to the Web 3.0
At F8 Facebook introduced the Open Graph, a new protocol that connects users to websites, books, movies, songs, events with Social Plugins that provide a personalized user experience.
Web developers can integrate the social graph to their websites with the Like button, the Activity Feed, the Facepile, the Recommendations plugin, the Like Box, the Comments and the Live Stream plugins that add a social layer to websites, personalizing users’ experience in exchange for their privacy.
Without the need of logging into Facebook on the website you are visiting, if you have logged into Facebook earlier in your browsing session you will be able to click on a Like button and create a connection between you and the page, or the item liked on a page, that is shared with applications and your Facebook friends: You will be able to see if your Facebook friends liked the page you are visiting, their comments and recommendations, unless you turn off Instant Personalization from your account’s privacy settings.
Semantic markup is used to specify the nature of the liked object (a movie, a book, a restaurant, etc.), and it’s the way Facebook can take advantage of its growing 400 million user base to collect structured data and target users effectively.
User profiling and ad targeting will benefit enormously by the amount of data Facebook will be able to collect from all the websites implementing Social Plugins. Whether this will be just the next step in Facebook monetization strategy or the beginning of Web 3.0 it’s impossible to tell, but many analysts believe that, with the Open Graph API, Facebook will become a semantic search engine and own our online identities.
