Before the Twitter revolutions, there was the Usenet revolution

Kremvax, the link between Relcom and the West
Polina Antonova
Perhaps the first example of network citizen journalism was during the August 1991 coup attempt by eight high level Soviet officials. There were two days of confrontation between demonstrators and troops, during which all Russian media except Usenet news groups were shut down by the authorities. Usenet, a precursor of today's Internet discussion forums, carried traffic into, out of and within Russia (70 cities) during the days of the coup attempt.

One of the quotes from that time foreshadows the Internet shut down in Egypt today. Polina Antonova of RELCOM, the Unix distributor that operated the network wrote:
They try to close all mass media, they stopped CNN an hour ago, and Soviet TV transmits opera and old movies. But, thank Heaven, they don't consider RELCOM mass media or they simply forgot about it.  Now we transmit information enough to put us in prison for the rest of our life.
After two tense days, the coup failed and president Mikhail Gorbachev was restored to power. For more on the role of the network during the coup attempt, see:
The following video clip (3:13) was part of a documentary on the Internet. (It includes a short interview of me at the time -- no white hair :-).

Tablet PCs will impact education, but it will take time.

Many new tablet computers were announced at the Consumer Electronics Show last week.  Walt Mossberg of the Wall Street Journal predicted that they will flood college campuses.

I agree that we will soon see students and professors carrying iPads and other tablets on campus, and, in the long run, I think we will view, annotate, discuss and share most of our teaching material on tablet-like devices.

But that is the long run -- they will not be part of mainstream education for many years.

Mainstream impact requires ubiquity.  Today, chalk and white-boards are ubiquitous.  We take them for granted and use them in every class.  Internet-connected computers with overhead displays are becoming widespread, and will also be taken for granted in the classroom.

Ubiquitous hardware is necessary, but not sufficient to drive major educational impact.  Standards are also needed.  The chalkboard works because we assume everyone speaks English or another language, and PowerPoint and Flash video are widely accepted standards for the classroom PC with a projector.

It will be some time before we can assume that nearly everyone has a tablet computer with a fairly standard hardware configuration.  It will take even longer to settle on standard formats for storing, annotating, and sharing teaching material.

Once the machines and standards are in place, we will see a significant impact on mainstream education, but that will not happen over night.

In general, we underestimate the time for a promising new technology to be adopted, but we also underestimate the extent of its impact on our lives, organizations and society when it is finally applied. I think this will hold true for tablet PCs in education.
