The online genres of blogs and wikis like Wikipedia can help focus on some taken-for-granted aspects of language in social interaction becoming important in political, social and economic spheres--aspects often eclipsed by a fixation on the technology. Myers (rhetoric and communication, Lancaster U., UK) analyzes the dimensions of these distinctive types of text, devices used to address an intended audience and convey stances, and debates, e.g., over whether Wikipedia should have a 'Neutral Point of View' (NPOV). The book includes examples, notes on student projects, blog addresses, and a glossary. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
