"Blogs are exciting many people in the business world, including many PR practitioners," reports Keith O'Brien. For business communicators, "blogs are a combination of many things: a kind of online networking cocktail reception where everyone seems to have a copy of the article they were referencing handy in their purse or briefcase, an easier and less-intrusive form of boosterism, and, as many will claim, an opportunity to further public discourse on the industry." Examples include PR Machine [3], Steve Rubel's Micro Persuasion [4], and Media Culpa [5], by Swedish PR practioner Hans Kullin.
