Scott Granneman has an excellent editorial on the risks of DRM at SecurityFocus; Soctt's an educator and a security expert, and his perspective on this is informed by both those careers:
The final indignity is that, although other DjVu readers provide for text selection, The New Yorker has removed that feature from its DjVu reader. You can print, but you can't select or copy. As a teacher of several technology courses at Washington University in St. Louis, this limitation, frankly, completely sucks. Suppose I want my students to read ten paragraphs from a New Yorker story that I provide on a password-protected web page. Too bad! I want to copy and paste some sentences into a presentation? Nope! A student expresses an interest in a topic, and I want to send her a New Yorker article via email that would help further her education? No can do.Link (Thanks, Scott!)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
