I'm from an African country where Whatsapp has played a major role in the political uprising against autocratic governments. Its power to mobilize the masses to go on the streets and protest is incredible. Radios and TV stations couldn't do that due to the pressure and their fear of being shut down by authorities. But Authorities have found a way to mute Whatsapp: shutting down the Internet. Just search : "Internet or Whtasapp shut down in Cameroun, Gabon, DR Congo or Togo" to find out. We are currently looking for alternatives to Whatsapp messenger that can work even when the Net is down. Suggestions are welcome.
