137 12.6 Informal Sources
Informal sources may produce publications in the form of blogs, personal websites, and related “non-official” documents. For example, a retired professional football player may produce a blog about his health challenges since retirement, and some of that information may be related to head injuries. These sorts of informal publications would provide insight into individual experiences, but you would need to supplement these publications with information from more formal sources before including any of it in a media message.
