The document discusses whether existing theories of public interest groups and collective action are sufficient to describe groups and public engagement on the internet. It argues that cases like MoveOn.org in 2004, the 2008 Obama campaign, and activism around net neutrality suggest not. These examples imply that political science theories do not fully capture how online technologies are changing the nature of social movements and public participation in unanticipated ways. A revised view of collective action may be needed, though it is unclear if online movements should be considered public interest groups in the traditional sense. This has implications for understanding public opinion and policy issues relating to the internet.
