Social media is a fast-growing trend in all aspects of our lives. It can be a very
effective way of communicating about water-related
issues, events, and facts, and can even be used in emergencies,
as shown in the recent tsunami disaster in Japan, and in Hurricane Irene.
(Twitter is a medium in which short messages of 140 characters or less are transmitted. The source of the "tweet" is denoted by
an "@" before a name, and messages from a given group or author's "profile" are listed chronologically, with the latest at the top.)
