Facebook is going to start
sharing app and Web browsing history it collects with advertisers to
display more targeted ads. This includes all those non-Facebook sites you visit. If this skeeves you out as much as it does me, you can opt out, kind of.
Facebook describes the feature this way on its security and privacy settings page: "You might visit a company's website that uses cookies to record visitors to it. The company then asks Facebook to show their ad to this list of visitors, and you might see these ads both on and off Facebook."
