The intensifying battle over Internet freedom

[Commentary] The Internet is both the vehicle and the battleground for freedom of expression around the world. The struggle between writers and governments over this free flow of information has escalated this past year and promises to intensify. Those supporting open frontiers for ideas and information need to be on high alert and take steps necessary to protect those silenced and to keep the Internet unencumbered. Last year became the first time that more Web journalists were jailed than those working in any other medium, according to the Committee to Protect Journalists. China, Burma, Vietnam, Iran, Syria, and Zimbabwe have led the clampdown. They have arrested writers, blocked websites and Internet access, set strict rules on cyber cafes, and tracked writers' work. In response, some writers have used proxy search engines, encryption, and other methods to try to get around censorship and detection.
