In Britain, a 'block list' of harmful Web sites, used by all the major Internet Service Providers, is maintained by a private foundation with little transparency and no judicial or government oversight of the list.

Many of the Kuomintang elite in Taiwan have relatives among the ruling elite here on mainland China.

Taiwan politics certainly is colorful.

There is a great deal of concern in the Chinese military that Taiwan's reunification with China is drifting further and further away.

Radio was used powerfully by Josef Goebbels to disseminate Nazi propaganda, and just as powerfully by King George VI to inspire the British people to fight invasion.

The Egyptian Revolution makes it clear, if anybody was in doubt, that digital technologies are going to play a powerful role in the future of global politics.

What role did the Internet play in the Egyptian Revolution? People will be arguing about the answer to that question for decades if not centuries.

Citizens continue to demand government help in fighting cybercrime, defending children from stalkers and bullies, and protecting consumers.

Governments clash with each other over who should control the co-ordination of the Internet's infrastructure and critical resources.

I think one of the problems I think with a lot of people in high school is that people don't think of the Internet as a real place or a place that has physical consequences in the physical world. This happens with adults who ought to know better, too.

In January 2012, Google Plus started to roll out support for nicknames and pseudonyms, but those registering with a name other than their real-life one must be able to prove that they have been using that alternative name elsewhere, either on the Web or in real life.

Nobody is forcing anybody who is uncomfortable with the terms of service to use Facebook. Executives point out that Internet users have choices on the Web.

As a condition for entry into the Chinese market, Apple had to agree to the Chinese government's censorship criteria in vetting the content of all iPhone apps available for download on devices sold in mainland China.

If multi-stakeholder Internet governance is to survive an endless series of challenges, its champions must commit to serving the interests and protecting the rights of all Internet users around the world, particularly those in developing countries where Internet use is growing fastest.

Defending a free and open global Internet requires a broad-based global movement with the stamina to engage in endless - and often highly technical - national and international policy battles.

A number of countries, including Russia and China, have put forward proposals to regulate aspects of the Internet like 'crime' and 'security' that are currently unregulated at the global level due to lack of international consensus over what those terms actually mean or over how to balance enforcement with the protection of citizens' rights.

President Barack Obama's administration sometimes finds itself at odds with members of Congress who oppose nearly everything the United Nations does on principle.

Political activists in Hong Kong and Taiwan use Facebook as their primary tool to mobilize support for their causes and activities.

Facebook is blocked in mainland China, but is used heavily by the rest of the Chinese-speaking world, including Hong Kong, Singapore, and Taiwan.

Facebook is not a physical country, but with 900 million users, its 'population' comes third after China and India. It may not be able to tax or jail its inhabitants, but its executives, programmers, and engineers do exercise a form of governance over people's online activities and identities.

Only about 10 percent of India's population uses the web, making it unlikely that Internet freedom will be a decisive ballot-box issue anytime soon.

Like it or not, Google and the Chinese government are stuck in a tense, long-term relationship, and can look forward to more high-stakes shadow-boxing in the netherworld of the world's most elaborate system of censorship.

While Google no longer has a search engine operation inside China, it has maintained a large presence in Beijing and Shanghai focused on research and development, advertising sales, and mobile platform development.

Clear limits should be set on how power is exercised in cyberspace by companies as well as governments through the democratic political process and enforced through law.
