It&#x27;s a matter of geometry and not loading up the phone lines with un-necessary calls.<p>If 1,000,000 people try to figure out whether the 1 person they know in a city of 2,000,000 are ok within a very short time-frame then the phone network will stop functioning.<p>A place to post a simple &#x27;I&#x27;m ok&#x27; will cut down tremendously on the number of calls that will then still need to be made. Unfortunately (1) not everybody has facebook and (2) a &#x27;no show&#x27; will now certainly lead to a phonecall when before it would be assumed the person was ok so I&#x27;m not sure whether it helps or not but the basic idea is probably a good one. It would be even better if this functionality was available outside of having a facebook account.
