How has the read-write web impacted copyright?

From an e-mail this week, Nadine asks:
Could you elaborate about how wiki’s and blogs in education are impacted (or not) by intellectual property? One of my principals in my district is taking a class for her Doctorate. She is not involved with Web2.0 technology at all so she relies on me for all things technology. She's asked me this question several times. While sitting in a session this morning (at the time you were presenting), she once again told me that her professor is looking for more information.
I've given her a lot of info about the proliferation of open source - a collaborative, sharing culture and creative commons, which I think is pretty much all you have to know when creating content on a blog or wiki. Maybe I'm completely off base so I'd like if you could give me some more input on her behalf.
An interesting question (that I am sure I fully understand) meriting a discussion, I believe. I'll start it and hope others will contribute their ideas.
My sense is that the read-write web has created a good deal of urgency to everyone understanding and applying copyright law and fair use policies. What really separates Web 2.0 from Web 1.0 is that any idiot can publish of public content with no financial investment, no technical skills and no writing ability (or original thoughts). This means:
- that anyone who publishes ought to have a firm grasp on what is legal and ethical in regard to the use of others' intellectual property as a part of his own creation.
- that anyone who publishes ought to have a firm grasp on what IP protection he would like applied to his own work.
The biggest difference to me is not the copyright laws or how they are applied, but in the number of people who now need to understand and apply them on a very regular basis.
The increase in the number of people being impacted by copyright laws - either as producer or consumer - has given rise to some populist-type calls for reform - Free Software movement, Creative Commons, Electronic Freedom Foundation, etc. And the ease with which IP can be distributed online is forcing new economic models of how creators profit from their work.
Oh, Nadine, I suspect anyone smart enough to get a doctorate ought to be smart enough to realize he/she should know a little something about this Web 2.0 business and how it may impact education. But I hope this helps.
