Facebook May Be Leaking Personally Identifiable Info

 From Online Media Daily:
" For the report, "On the Leakage of Personally Identifiable Information Via Online Social Networks," two computer scientists from AT&T and Worcester Polytechnic Institute examined the type of information transmitted to ad networks from Facebook, MySpace and other social networking services.
The researchers concluded that many social networking sites "leak" personally identifiable information by including it in the HTTP header information that is automatically sent to ad networks."

This is just a little disturbing.
