The Chaos of the Internet as an External Brain; and More

From the early days of computers, people have speculated that computers would be used to supplement our intelligence. In the last decades, most of the work toward this dream has been in the form of trying to build artificial intelligence.

Social Media and the Twitter Backchannel at CHI2010

A marked difference at CHI 2010 compared to last year is the amount of research around social media and the use of social media during the conference. These practices are enabling the conference to be less about one-to-many lectures on the latest research and more about peer-to-peer interactions.

Time to Rethink Computer Science Education: The (Social) Web Changes Everything!

Let's rethink computer science education in face of Web 1.0, Web 2.0, and beyond. The Internet have changed everything we know about how computing is done. It's time to revamp the entire curriculum to make it more relevant to the new world.

The DARPA Network Challenge and the Design of Social Participation Systems

What have we learned from the DARPA Network Challenge and the design of social participation systems? The principal concern for designers of social participation systems is to ensure the participants both give and get something from the system that is beneficial to both the individual as well as to the group. Looking toward the next decade, the social computing research challenge is understanding how to replicate effective social actions in social participation systems, in domains such as healthcare, education, and open government.

Collective Intelligence: a Fad or Real Research?

A recent trend in HCI research is the extension of the long time goal of augmenting human intelligence to "augmenting social intelligence." That is, enabling not just a single person to find and make sense of information, but enabling a group of people (whether explicitly or implicitly organized) to make sense of information.
