释放吴皓Global Voices stalwarts Rebecca MacKinnon and Ethan Zuckerman have launched a blog (blocked in China - proxy link or alternate link) campaigning for the release of recently detained returnee Chinese filmmaker, blogger and fellow Global Voices editor Hao Wu.

The story of who Wu is and why he may have been detained are on the new site, and also on Rebecca's own blog. Among other things, Wu was working on a documentary about China's underground churches. MacKinnon fears that his siezed tapes may now be used to identify others for detention.

Please go have a read. Please also spare a thought for the many others who aren't fortunate enough to have organized campaigns for their release. Every voice that is silenced drags our often abstract discussions of censorship and morality back into cold, concrete reality.
