I think this is a great use of technology that can change the lives of its users forever. You can't get more disruptive then this.
I really hope it succeeds as I've become really worried about the number of suicidal posts I've seen on HackerNews lately. I've noticed on 3 separate occasions in the last month alone posts from severely depressed hackers usually titled something along the lines of 'want to give up'.
While I think its great that hackers can come together to support each other, I'm guessing most of us are not trained psychologists.
