Facebook users deliver a mountain of information about themselves to Facebook via their Facebook profiles. What somebody 'likes' on Facebook or shares on Facebook tells plenty about that individual.

With Facebook Open Graph, websites will be able to pull key information about a visitor using their Facebook profile, and show them information based on their interests, or their friends' interests.

For example, imagine you are about to buy a digital camera online. Next to the 'add to cart' button, you see that 8 of your friends have 'liked' this same digital camera, or better still, actually purchased this digital camera from the same store.

This is a personalised shopping experience for you; and it is also beneficial to the website store, as it increases the likelihood that you will actually purchase that digital camera also.

As with any time Facebook does something, the negative of Open Graph is with the Privacy of Facebook users.

Well, to complainants, I say get over it and get off Facebook. This is just the beginning.
