I've just found and joined this group. I gather that the top 10 tags in use may correspond to the sections and subsections of your chapter.

emerging concepts 52
emerging products: applications 32
emerging processes 26
emerging products: hardware 12
virtual worlds 12
online meeting spaces 11
mashups 11
other emerging technology resources 8
imagining technology in education tomorrow 8
intelligent searching 8

Are there any tags in the top 10 that are independent of sections and subsections, or other tags further down the list of frequency of use that correspond to sections or subsections?

Cheers, Paul
