"Blogs are more or less controllable for those who want to keep them under surveillance. Governments that are most up to do date with new technology use the most sophisticated filtering or blocking techniques, preventing them from appearing on the Web at all. But bloggers don't just sit back and let it happen. The essential question becomes how to blog in complete safety. With a normal IP address, a blogger can be tracked down and arrested. Anonymity allows them to keep their freedom.
In countries where censorship holds sway, blogs are sometimes the only source of news. During the events in Burma in the autumn of 2007, pitting monks and the people against the military junta, bloggers were the main source of news for foreign journalists. Their video footage made it possible to gauge the scale of the protests and what demonstrators' demands were. For more than two months, marches were held in the streets, then a massive crackdown was launched against opponents that only the Burmese were able to show, so hard did it become for the few foreign journalists who managed to enter the country to get back out with their footage. And bloggers could not get the footage out without getting round online censorship imposed by the government. This handbook seeks to help every blogger to fill in the "black holes" In news. The second part is devoted to techniques which can thwart filtering technology." (Page 4-5)
