“The Internet is a revolutionary instrument that permits the receiving and transmission of ideas, in both directions, that is something we should know how to use,” Fidel Castro told a crowd of supporters on Feb. 4, according to the state-owned Cuban newspaper Granma International. Castro, who made his first public appearance since April 2011, launched his two-volume memoir, “Guerilla of Time,” and took the opportunity to discuss issues of importance to him. Earlier this week, Miranda Neubauer reported that one of these topics was the need for the Internet. Castro has been a proponent of the Internet as a tool for the exchange of ideas since 2003, but the average Cuban citizen faces great difficulty getting online. GO
