It's highly unlikely that the "lifesaving" feature Zuckerberg referred to would relate to something so frivolous as shopping or gaming or networking; the fact that the announcement will be made on "Good Morning America" suggests it's not a major piece of technology — that would be saved for the f8 Developer's Conference — but it's big enough for a one-on-one interview at Facebook HQ. All things considered, this new "lifesaving" feature most likely relates to bullying and suicide prevention, and Facebook will likely announce a change to its software that relates to these initiatives. It could be that Facebook has finally created an algorithm that can detect suicidal thoughts or expressions: Even though nobody knows users better than their friends or family, users can shield themselves from even loved ones with certain privacy settings. The feature may raise some eyebrows, but it would also save the lives of bullied children, teenagers, and also their parents."
