I don't know if your question is genuine or whether you were more asking out of anger...it's different from the standpoint of editorial involvement. Fox News and MSNBC have editors who filter the majority of their content, while the users (readers) contribute, "feedback" in terms of what stories are, "hot/trending" as well as comments. In Twitter/Facebook these roles are reversed, with the users filtering the majority of the content, barring outright obscene content.
Fox News and MSNBC do have the option of pushing stories which change the conversation, thereby controlling how things are delivered on a story-by-story basis, like an art form whereas Facebook has dials and levers to tweak particular aspects of how sharing is done. I would say news content on Facebook is 90% sharing, 10% curation while news content on MSNBC and Fox are 80% curation and 20% sharing.
