"Increasingly I think the digital divide is less about access to technology and more about the difference between those who know how and those who don't know how," says author Howard Rheingold, speaking in front of King's College at Cambridge University. "The ability to know has suddenly become the ability to search and the ability to sift" and discern.

Earlier in the week Howard gave the keynote address at Reboot Britain, and he recounts some of them here. Among the Essential Literacies he cites are:

• Attention
• Participation
• Collaboration
• Critical consumption (which includes "crap detection" -- we live in an age when you can get the answer to anything out of the air, but how do you know what to trust?)
