It is important for readers to be able to read and gleam information from multiple sources and their respective mediums.
I find it interesting that Konnikova notes the tendency of readers to skim when reading digital documents versus more intense reading of tangible books, as well as readers' claims that it feels as though they have not actually read a document unless they have physically touched the paper. It could be argued that the majority of readers share in this opinion, and it creates some sort of aversion to reading digital documents.
Personally, I think that where many schools now provide new laptops to their students, or at the very least to their classrooms for shared use, it is vital that students learn how to appropriately and accurately read digitally.
Some people think that this is a downfall in our society because of how quickly it has changed before our eyes. Honestly, it is only a matter of time before textbooks become obsolete and all are available on all digital mediums, not just kindle. This being said, students have every right to be taught how to be active digital readers now, when it's reaching more fame.
