This is a great story on the benefits of using social media to keep in touch when phones are down and there is intermittent data service. Posting an update on facebook or sending a tweet can alleviate stress and worry of families across the globe. This should also be seen as a lesson for all travelers that when you do find yourself in a city that experiences a massive event like this and parents and families may worry after you please keep them informed and contact them. It is imperative to do this as soon as possible after the said event and make it public as possible meaning you may have friends that are also worried. So keep in touch when you travel and keep your family and loves ones just that little bit lower on the stress ladder.
