A method automatically and efficiently propagates information using previously established social methods of communication (e.g., email, instant messaging (IM), social network message posting, and short message services). In conjunction with the method, a system collects and disseminates information on a social network. The system includes: (a) a server for providing a user interface (e.g., a user facing web site) which allows a user to exchange information with one or more external services, wherein the information exchange includes receiving a message from the user that the user intends to disseminate through the external services; (b) a message module which prepares the message received from the user for dissemination; and (c) a communication module coupled to the user interface, the message module and the external services to mediate the information exchange between the user and the external services.
