Web 2.0 is an interactive social media that allows users to interact, collaborate and share information, connect with people online and enables users not only to read content but also create and share content. Social networks enable us to connect, collaborate and interact with other people even with people at great distances. Social networking tools enable people to create profiles, find other people and interact and in time form communities and these communities include professional networks, language specific networks, local networks and cause oriented networks. Friends can share, comment, tag and rate our videos and photos.
Social media tools are also useful to organizations that can be used to coordinate remote workgroup with other organizations and by using the features of planning, doing tasks together, communicating, sharing resources and collaboration. Organizations can publish their own news, communicate with people in other continents, to raise funds. Organizations should be careful what information to make available online and what not to.
