Would it have helped the families of first the first responders like NYFD/NYPD/EMTs? Are first responders supposed to take time to "check in" on FB? Would it have been any less chaotic for their families?
And honestly I find it really disturbing to compare tragedies, especially so in the context of their value to a FB feature.
I guess I feel I have the right to make the comparison. I wasn't there in NYC, but I had "some skin in the game" on 9/11 so to speak. From that experience, and from later ones, I can put myself into the shoes of somebody wondering if their loved one was mixed up in the London fire. To them, it doesn't matter that the fire affected only one apartment building in London.
This difference is my problem with the Safety Check system and, I believe, the authors. If there is an event where my safety is indeed in a majority questionable state (Typhoon takes out my town) then prompt me with a check #ThankYou. If there was an event which doesn't swing to a majority question then leave it to the individual case.
2 side notes: 1. Why do I personally take issue? Well, I was a student during the following: https://en.wikipedia.org/wiki/2016_Ohio_State_University_att... and felt "forced" to provide my answer to the Safety Check as I know my one crazy aunt would go loony if I didn't. In no way did the event warrant this switch from perceived safety to opt-in safety (it was 13 students hurt of >50,000).
2. As other commenters have noted "With great power, comes great responsibility!". If they're going to deploy this technology make sure it provides value and effects, changes safety to opt-in, for the smallest possible subset. Additionally, as you pointed out in your original post allow individuals to add themselves to the Safety Check list if you are getting spammed with messages.
Sorry for the long post but, like the author, I was very taken aback when I first encountered this feature on Facebook. While I understand the good intentions. Personally, it fell into the area of prompting a world where we need that instant knowledge, text back, response, etc. which frankly isn't that healthy...
After reading all the comments my observations kicked off, your's actually caused me to think outside of my own set of experiences. I kinda see your point. That said, I still stand by my original position that FB's service fills a purpose at the Katrina / regional earthquake & tsunami level. However perhaps they need to work on the fine tuning. Personally glad I don't work in this area inside FB! They are going to be criticized for setting the threshold too high or too low regardless.
Hypotheticals about how 9/11 would have played in the presence of a safety notification by facebook are conjecture, and seem pretty far fetched to me.
The reality is the vast majority of people are getting drawn in, dishonestly, into interaction with FB.
It happened in my city also, a underground subway was getting constructed, not even used by people yet, and a small portion collapsed. Almost everyone in the city got a safety check notification, hundreds of thousands of people, for an event that killed no one, and only affected a handful of workers. Why is it necessary to notify the city of that? It's irresponsible and dishonest.
