comp.risks is something I've been following avidly for the past 4 years. It's a moderated / digested list that discusses and exposes risks involved when people rely on computer hardware and software and how to avoid or design around these risks. On USENET, it is available as comp.risks.

Officially known as the FORUM ON RISKS TO THE PUBLIC IN COMPUTERS AND RELATED SYSTEMS the first digest was sent by the Editor Peter G. Neumann August 1, 1995.
