I actually have no idea what the answer to that question is. I already mentioned the essay about the Clash which was about corporate rock, politics, and the reality of growing up in Canby, Oregon.
But there’s also this short movie that the Willamette Valley Film Collective made last year to compete in the International Documentary Challenge. The Willamette Valley Film Collective membership varies, but the IDC competition has been a regular feature of hte WVFC’s schedule every year.
Last year we looked at an exhibit of punk rock art at the library at Western Oregon University. Shaun has put a couple of versions of the final product up on his channel at Blip-TV.
We edited this video between the hours of 11 pm and 5 am. And there’s a lot about the process I don’t remember that well. But what I do remember, and what I think is fairly tightly connected to the edupunk ideas that have been so well-discussed online over the last few days is in the description of the DIY aesthetic. As you can tell, that was a strong theme throughout the discussion of the meaning of punk, and of the meaning of punk rock art. And I think, *think* – it gets at some of the reason this term is resonating with people, at least a certain subgroup of people, around the web.

I second your emphasis on punk as a DIY movement – if you’re tired of what the corporate Powers that Be are providing for you, don’t wait for them to change, make your own. And that does seem to be where the “edupunk” appeal comes from, but is also part of what people who are uncomfortable with the term might be missing.
