Each blog has a unique author each with a unique perspective. This perspective should be retained as a selling point of any blog, and an additional way to attract readers. As an informal means of communication, personal bias and opinion can enter into writing a blog, but should be held in check so as not to eliminate all credibility. Given anonymity, the blogger should preface any personal narratives with the necessary background information. The style of the text indicates a great deal about the purpose behind the blog. A more professional tone can create the illusion of credibility, while a more personal tone can create a better rapport between blogger and audience. There is a fine balance between sounding overly academic and being too informal.
