In short, the Web 2.0 models the very active engagement that is central to the learning paradigm.

If one studies this table long enough, a gestalt emerges: the Web 1.0 looks uncannily like the teaching paradigm, whereas the Web 2.0 resembles the learning paradigm.

The opportunity lies in students being able to engage in activities and create content that lives outside the course site—in their own space, a space that is a resource and staging ground for their work across their entire academic career.

One thing that we have learned in our industry is that people have a lot to say. They are using the Internet to publish things at an astonishing pace. 120K blogs are created daily — most of them with an audience of one. Over half of them are created by people under the age of nineteen. In the US, nearly 40 percent of Internet users upload videos, and globally over fifteen hours of video are uploaded to YouTube every minute. The web is very social too: about one of every six minutes that people spend online is spent in a social network of some type.

No one argues the value of free speech, but the vast majority of stuff we find on the web is useless. The clamor of junk threatens to drown out voices of quality.

When data is abundant, intelligence will win

The real potential of cloud computing lies not in taking stuff that used to live on PCs and putting it online, but in doing things online that were previously simply impossible.

Oil fueled the Industrial Revolution, but data will fuel the next generation of growth.

Now, the best technology starts with consumers, where a Darwinian market drives innovation that far surpasses traditional enterprise tools, and migrates to the workplace only after thriving with consumers.

Cloud computing levels that playing field so that the small business has access to the same systems that large businesses do. Given that small businesses generate most of the jobs in the economy, this is no small trend.

With facts, negotiations can become less about who yells louder, but about who has the stronger data.

Similarly, we manage Google with a long-term focus.

We will have to accept that privacy as we have heretofore understood it may be a thing of the past:

We will have to accept that privacy as we have heretofore understood it may be a thing of the past: that people will be presented with a bargain where access to the most intimate details of their lives is traded away in return for increased convenience, and that many will accept.

We hear about RFID tags being integrated into employee ID cards, a new modular sensor grid on the architectural market, a networking scheme proposing to use the body's own electrical field to carry information - and this in the general press, not the specialist journals.

t is coming - and as yet, the people who will be most affected by it, the overwhelming majority of whom are nontechnical, nonspecialist, ordinary citizens of the developed world, barely know it even exists.

It is coming because something like it effectively became inevitable, the moment each of the tools, products and services we're interested started communicating in ones and zeroes.

But the technology we're discussing here - ambient, ubiquitous, insinuative into all the apertures everyday life affords it - will be environment-forming in a way neither of those are.

ubiquitous computing is; establish that it is a very real concern for all of us,
