This is very timely and wise advice!!! I had not really thought about the value of all the contacts I have made in facebook- most of them I do not have e-mails or other contact info for... college friends who are overseas etc, that I had lost track of until recently.

I just had my students do a survey of their own data, what do they have, where is it, is it secure, and its value. None of us thought of these social networking items.

I really preach not trusting data you are responsible for or depend on to ANYONE else, least of all "IT" departments.

This is a very large down side to the rehash and repackaging of old ideas as "cloud computing"
