The power of social media in education and elsewhere derives from their affordances for forms of communication and social behavior that were previously prohibitively difficult or expensive for more than a tiny elite to benefit. Forums afford many-to-many, multimedia, asynchronous discussions among small or large groups, regardless of distance, over extended periods; blogging affords the expression of individual voice, the emergence of a market for intelligent information-filtering and knowledge-dissemination, and public interactions in the form of comments; wikis enable collaborative document and knowledge creation as well as web-building as a learning method; social bookmarking makes possible simple, bottom-up, collective knowledge-gathering; microblogging and chat add synchronous online text channels that can be tuned and cultivated for specific purposes.
