Let me take a crack at this, then.
- Health blogs should provide short articles on specific topics. Ideally, they should include pictures or photos and links to expert sites for more information. For example, a writer may create a cancer blog with varied articles, but link to their photoblog, providing cancer and cancer related photos.
- Health blogs should allow the reader to interact with the writer/blogger through either a forum or email.
- Health blogs must avoid giving a reader the impression that the articles are giving a diagnosis or sound medical advice. Always include a line or phrase advising the reader to seek the advice from a doctor or medical professional and to discuss the article with them. Remember: giving the wrong impression in this area could result in very serious consequences for the writer, the publication and the reader (s).
