There are lots of difference between social media and other media. Perhaps the biggest difference between traditional media (newspapers, television, radio, books, etc.) and social media is the dynamic and flexible nature of the latter. Social media can change with time and be edited by the author and, in some cases, the community. Likewise, the audience can interact with and republish social media. It lends itself to being archived, indexed by search engines, and shared by users in many ways.
