As the area of online social networking develops and many online services add social features to their offerings, the definition of online social networking services broadens. Online social networking services range from social interaction-centered sites such as Facebook or MySpace, to information dissemination-centric services such as Twitter or Google Buzz, to social interaction features added to existing sites and services such as Flickr or Amazon. Each of these services has different characteristics of social interaction and different vulnerabilities to attack.
