Via David Pogue's technology blog comes Enron Email.
Search through more hundreds of thousands of email messages to and from 176 former Enron executives and employees from the power-trading operations in 2000-2002.For the first time, they are available to the public for free through the easy-to-use interface of the InBoxer Anti-Risk Appliance. Create a free account, and go to work. You can search for words, phrases, senders, recipients, and more. (Lots of stuff in there. We found a copy of a message regarding Tom DeLay and political contributions for use in Texas.)
Or, use the built in tools to find offensive messages, personal messages, and others that would have triggered an alert if Enron had been using the InBoxer Anti-Risk Appliance back in 2000-2002, and can alert companies to similar risks, if they happened today.
