The future of the internet

Fifteen years ago internet was a wide-open space, a new frontier. For the first time, anyone could communicate electronically with anyone else—globally and essentially free of charge. Anyone was able to create a website or an online shop, which could be reached from anywhere in the world using a simple piece of software called a browser, without asking anyone else for permission. The control of information, opinion and commerce by governments—or big companies, for that matter—indeed appeared to be a thing of the past.

The lofty discourse on “cyberspace” has long changed. Today the “cloud” is code for all kinds of digital services generated in warehouses packed with computers, called data centres, and distributed over the internet. Most of the talk, though, concerns more earthly matters: privacy, antitrust,...

This is a fair reflection of what is happening on the internet. Fifteen years after its first manifestation as a global, unifying network, it has entered its second phase: it appears to be balkanising, torn apart by three separate, but related forces:
  • First, governments are increasingly reasserting their sovereignty. Recently several countries have demanded that their law-enforcement agencies have access to e-mails sent from BlackBerry smart-phones.
  • Second, big IT companies are building their own digital territories, where they set the rules and control or limit connections to other parts of the internet. 
  • Third, network owners would like to treat different types of traffic differently, in effect creating faster and slower lanes on the internet.
The open internet has been a boon for humanity. It has not only allowed companies and other organisations of all sorts to become more efficient, but enabled other forms of production, notably “open source” methods, in which groups of people, often volunteers, all over the world develop products, mostly pieces of software, collectively. Individuals have access to more information than ever, communicate more freely and form groups of like-minded people more easily.

However, this very success has given rise to the forces that are now pulling the internet apart.  The internet is too important for governments to ignore. They are increasingly finding ways to enforce their laws in the digital realm. The most prominent is China’s “great firewall”. The Chinese authorities are using the same technology that companies use to stop employees accessing particular websites and online services. The Australian government plans to build a firewall to block material showing the sexual abuse of children and other criminal or offensive content.

Many media companies  have already gone one step further. They use another part of the internet’s address system, the “IP numbers” that identify computers on the network, to block access to content if consumers are not in certain countries. Try viewing a television show on Hulu, a popular American video service, from Europe and it will tell you: “We’re sorry, currently our video library can only be streamed within the United States.” Similarly, Spotify, a popular European music-streaming service, cannot be reached from America. The trend to more closed systems is undeniable.

Facebook, the web’s biggest social network is a fast-growing, semi-open platform with more than 500m registered users. Its American contingent spends on average more than six hours a month on the site and less than two on Google. Users have identities specific to Facebook and communicate mostly via internal messages. The firm has its own rules, covering, for instance, which third-party applications may run and how personal data are dealt with.

If operators were allowed to charge for better service, they could extort protection money from every website. Those not willing to pay for their data to be transmitted quickly would be left to crawl in the slow lane. “Allowing broadband carriers to control what people see and do online would fundamentally undermine the principles that have made the internet such a success,” said Vinton Cerf, one of the network’s founding fathers.

David McCandless: The beauty of data visualization

David McCandless turns complex data sets (like worldwide military spending, media buzz, Facebook status updates) into beautiful, simple diagrams that tease out unseen patterns and connections. Good design, he suggests, is the best way to navigate information glut -- and it may just change the way we see the world.

McCandless' genius is not so much in finding jazzy new ways to show data -- the actual graphics aren't the real innovation here -- as in finding fresh ways to combine datasets to let them ping and prod each other

As Taciano Moraes wrote down in the discussion section, the most interesting on this talk was that changing the way of visualizing information we can reach another level of comprehension and generate a new kind of (more) information:
  • Looking closer we can discover details.
  • Looking wider we can discover patterns.
In this time of information overload, we just have to pay some attention on how to look at it to find what we want it.

Facebook: The future is another country

Despite its giant population, Facebook is not quite a sovereign state—but it is beginning to look and act like one. If it were a physical nation, it would now be the third most populous on earth. Mr Zuckerberg is confident there will be a billion users in a few years.




Facebook has certainly tried to guide the development of its online economy, almost in the way that governments seek to influence economic activity in the real world, through fiscal and monetary policy. Earlier this year 2010, the firm said it wanted applications running on its platform to accept its virtual currency, known as Facebook Credits. It argued that this was in the interests of Facebook users, who would no longer have to use different online currencies for different applications. But this infuriated some developers, who resent the fact that Facebook takes a 30% cut on every transaction involving credits.
