How to opt out of Facebook sharing option.

With the announcement last week by Facebook of the expansion of its "Like" program to other sites, little notice were made of the possible ramifications of such program. The program works by allowing outside participant sites to embed Facebook Like button on their sites. Once embeded, the button will appear on its page of the site and will give Facebook members a chance to click on it when they see something that they like. That seemingly harmless action will have a lot of ramifications since since that one click will essentially broadcast the user action to his or her network through his or her newsfeed. Also, all the names of the user Facebook friends who have already clicked on the button, will be broadcasted alongside.
In conjunction of the new Like program, Facebook has launched a new innovation called Open Graph which is a technology that allows certain sites like Pandora, Yelp, and Docs by Microsoft, to personalize their offerings to users based on the information stored in their personal profiles. That level of personalization is possible because Facebook gives those sites access to those users information. Ant that's where it gets scary for unscrupulous users who unwillingly may be giving away access to their personal information.
As you may have noticed, the opt-in option is by default and users who do not want their information accessed that way, have the means to opt-out.
You can either turn Instant Personalization off entirely at Facebook, or you can opt out at individual websites on a case-by-case basis. The latter is easy; the first time you arrive at a website that uses Instant Personalization, a bar will appear at the top of the page letting you know that’s what’s happening and giving you the option to either accept that or not.
To opt out of the personalization feature altogether, you can do so by going to Facebook home page, access your "Account" and click on "Privacy Settings."
