Social networking sites allow users to create personal profiles and connect with other users to interact and share content. Some early social networking sites included Classmates, Six Degrees, and Friendster. Social media refers to online media that enables user interactivity through blogs, videos, and photos. While social networking and media allow connecting with others and sharing ideas, there are also concerns about overuse reducing real-world social skills and privacy issues with sharing content online. Educators should use social technologies strategically to enhance learning rather than for their own sake.
