It seems Paul is assuming that the purpose of the group is not to share sites on Education-as most of us have believed so far-but to share sites on the use of Diigo in Education.

I think you should read the comments to the article ;-) I would say that if we apply old test to new behaviours the latter may get worse results than previous behaviours tailored to meet the tests. Furthermore, if Internet is so distracting, and our students are going to lived in an Internet-ised world the rest of their lives, should not be training them to be better users of it rather than artificially isolate them?
