blog for BBC. A blog writer is using the technology to create a message that is in some ways like a newsletter and in other ways, like a personal letter. "The greatest difference between a blog and a photocopied school newsletter, or an annual family letter photocopied and mailed to a hundred friends, is the potential audience and the increased potential for direct communication between audience members". Thus, as with other forms of letters the writer knows some of the readers, but one of the main differences is that "some of the audience will be random" and "that presumably changes the way we [writers] write." It has been argued that blogs owe a debt to Renaissance essayist Michel de Montaigne, whose Essais ("attempts"), were published in 1580, because Montaigne "wrote as if he were chatting to his readers: just two friends, whiling away an afternoon in conversation". Columnist Columnists write regular parts for newspapers and other periodicals, usually containing a lively and entertaining expression of opinion. Some columnists have had collections of their best work published as a collection in a book so that readers can re-read what would otherwise be no longer available.

An example is the female columnist Elizabeth Farrelly, who besides being a columnist, is also an architecture critic and author of books. Diarist Writers who record their experiences, thoughts, or emotions in a sequential form over a period of time in a diary are known as diarists. Their writings can provide valuable insights into historical periods, specific events, or individual personalities. Examples include Samuel Pepys (1633–1703), an English administrator and Member of Parliament, whose detailed private diary provides eyewitness accounts of events during the 17th century, most notably of the Great Fire of London. Anne Frank (1929–1945) was a 13-year-old Dutch girl whose diary from 1942 to 1944 records both her experiences as a persecuted Jew in World War II and an adolescent dealing with intra-family relationships. Journalist Journalists write reports about current events after investigating them and gathering information. Some journalists write reports about predictable or scheduled events such as social or political meetings. Others are investigative journalists who need to undertake considerable research and analysis in order to write an explanation or account of something complex that was hitherto unknown or not understood. Often investigative journalists are reporting
