I think social media is any forum online that has more than one participant. It is a place where writers and readers alike can exchange conversation, comments, and ideas. While social media is real time, at the moment, the past is usually accessible to view. This “old news” can become current news again if someone chooses to bring it back into current discussion. Blogs are a form of social media. They allow an exchange between writer and reader in the comment section of the blog. Typically bloggers post on a regular basis, making what they post current information. But, blogs also allow readers to go into a blog’s archives, allowing old information to be accessed. Rehashing older blog information can make it new again.
