Digital information about people after they pass away

A few weeks ago entertainer Clay Cole passed away while his Facebook profile is still intact.  Likewise my brother-in-law Paul Shapiro who sadly left us is still on Facebook.  The entire issue of "internet mortality" is addressed in this article in Sunday's New York Times magazine.  Likewise what will happen to blogs, web sites, and Twitter posts long after the writer passes on.  I will refer my reader to this excellent article by Rob Waker.
