The Electronic Frontier Foundation just launched "TOSBack: The Terms-Of-Service Tracker" which gives you realtime feed of the changes to terms of service in 44 online services (you know, all those sites whose terms are "subject to change without notice"). I want one of these that tell you which bits are enforceable.
"Terms of service form the foundation of your relationship with social networking sites, online businesses, and other Internet communities, but most people become aware of these terms only when there's a problem," said EFF Activism and Technology Manager Tim Jones. "We created TOSBack to help consumers monitor terms of service for the websites they use everyday, and show how the terms change over time."
At www.TOSBack.org, you can see a real-time feed of changes and updates to more than three dozen polices from the Internet's most popular online services. Clicking on an update brings you to a side-by-side before-and-after comparison, highlighting what has been removed from the policy and what has been added.
