Social media often feeds into the discovery of new content such as news stories, and “discovery” is a search activity. Many people also perform searches at social media sites to find social media content For instance, Twitter is a social site to share short messages

Social connections may also impact the relevancy of some search results, either within a social media network or at a ‘mainstream’ search engine. Social media itself is a catch-all term for sites that may provide radically different social actions.
