The Electronic Frontier Foundation (EFF) has created a new web site, Surveillance Self-Defense (ssd.eff.org). The site collects information about surveillance techniques that governments, large companies, marketing firms, criminal organizations, and some individuals are using to track you through the day. It then tells you how to guard against and to some extent prevent that surveillance, or at least keep private those parts of your life that you want to be private.
Bravo! And thanks, EFF. :-)
