Online participation is used to describe the interaction between users and online communities on the web. Online communities often involve members to provide content to the website or contribute in some way. Examples of such include wikis, blogs, online multiplayer games, and other types of social platforms. Online participation is currently a heavily researched field. It provides insight into fields such as web design, online marketing, crowdsourcing, and many areas of psychology. Some subcategories that fall under online participation are: commitment to online communities, coordination and interaction, and member recruitment.
