Writing about the Great Firewall of China, I've concluded that no matter what measures the governments put in place to block freedom of speech, people will always find a way to communicate. I'm even more sure of that now, because I see an emerging trend, driven by social media, to use, create, and educate about various tools that people can use to circumvent censorship and remain anonymous while browsing the web.
Besides the already existing tools such as anonymizers, various proxies, and Tor, which are now gaining prominence, I've seen a number of almost simultaneous similar initiatives. The idea to turn Opera Unite into a web proxy for Iran is one such idea, which will undoubtedly (save possible technical limitations) quickly be turned into reality. There's also the recently launched beta of Ipredator, The Pirate Bay's stab at creating a secure VPN for everyone.
