Dead links

I actually have a few notes on a potential play dealing with how web accounts live on after a person dies, but I've just had my first personal brush with the phenomenon.

I found out that one of my professional contacts on LinkedIn passed away several weeks ago. Naturally, his LinkedIn profile does not indicate this, even in the "What are you working on now?" box. I doubt his family will worry about about removing his profile, even if they know it is out there. As a result, my professional network is likely to include a dead man for quite a while.
