Ask questions thru your ebook and author answers in the margins

Get Will Hermes’ book Love Goes to Buildings on Fire via Copia and ask questions and get answers in the margins of the eBook. Good for those purchasing the book by February 21, 2012. http://www.mediabistro.com/ebooknewser/will-hermes-to-answer-reader-questions-in-margins-of-copia-ebook_b20086 Copia is using this to show off the note-taking, bookmarking, and highlighting capabilities of their desktop (and Android) reader. Readers can sync everything to their online account and share with friends. Doesn't that make great sense for a textbook? Students could ask context-sensitive questions and get answers related to the text and Other students could see the answers? Can your friends be your classmates and no one else? I'm going to have to give this a look.
