Wikis, blogs and product review sites provide q asynchronous platforms for sharing digital content. A wiki is a real-time editable website that helps users create content through cooperative development and ownership (Bean and Hott, 2005). The term blog is a contraction of the phrase "web log" and refers to a personal website or webpage that allows an individual to present content and opinions. The key difference between a wiki and a blog is that one author controls the content on a blog, whereas a wiki supports multiple authors. A product review site is a website devoted to providing subjective consumer feedback on products and services
