The latest issue of Webology has an emphasis on folksonomies and something on Web 2.0. There is also an article:
Aitken, W. (2007). "Use of Web in Tertiary Research and Education." Webology, 4 (2). http://www.webology.ir/2007/v4n2/a42.html
This is interesting in actually putting the case for use of the web by students. It describes the example of undergraduates in Aboriginal Studies (in Australia), who were originally discouraged from using the web, but this author explains the advantages. One of the things she raises is how discovering and reflecting on what search terms do, and don't, work can be valuable (e.g. that government agencies talk about air quality rather than air pollution). She also talks about how the usage of words such as "aboriginal" and "indigenous" in websites is interesting to study in itself, with social/political implications.
