Google's copyright paranoia

Lessig's Free Culture book has been released under a Creative Commons license. So how come Google Print's three editions consist of one limited preview and two no previews??

Help pretest my survey

A crucial part of my PhD thesis is a survey for movement activists about their usage of communication tools. A crucial part of that is that the survey must be as clear and as short as possible. Here's where I need help: I need a few kind souls to read through the survey (link), and to note any parts that are confusing, contain errors (I am not a native English speaker...), and let me know how long did it take you to complete the survey (I hope that it is doable in ~20 minutes).

You can reach me by commenting here, at my Wikipedia talk page, at Facebook, or at piokon at post dot pl. Thanks,
