It was with great sadness that I learnt about the death of Rob Williams of Dolphin Music. I did not know the man himself, but knew he was part of a skiing party in Verbier. It seems he got separated from his group and died overnight.
His colleagues had tried to locate him using Twitter, iPhone GPS and other technologies to no avail. His colleague Jason Tavaria was rescued by Verbier's Mountain Rescue patrol (though it is not known if the any Web 2.0 technology helped save him).
What is surprising is how quickly the story came to light as members of the group Tweeted their concerns.
Again condolences to the family/friends and colleagues of Rob.
