Google has hosted many humanitarian services. The focus previously was on providing urgent information (Victorian Bush Fires[1]) or re-uniting dislocated people (Google Person Finder[2]) during these disasters.

Messages for Japan instead shows the sorrow and compassion evoked from around the world. Many have lost all that they've ever known or loved; to know you remain connected in this world is so utterly important.
