With the release of the Facebook's "Like" button, Facebook has supplementally added new plug-ins that will change the way that people socialize. One of the key plug-ins will allow different sites to add a plug-in that will enable Facebook users to go into a site and to see which of their friends have visited the site. In addition, the Facebook user will be able to see what their friends liked in the site.
One of the sites that will be affected is Pandora--the online, music request station. The social plug-in will allow users to see which of their friends like the same band and what other bands their friends liked listening to. This will enable Pandora to know what new user like without requiring them to type in their preference.
The only question is how will users feel as their information is shared across websites of different brands and organizations?
