Hi Spam Apprentice, Sure. I think that teachers would like to eliminate aspects of Evernote that might potentially distract from their students' learning. Students are encouraged to use Evernote in the classroom as a note-taking device, and they are not using it as a collaborative tool (although they might if they wish). The Chat function on Evernote has no added benefit in their opinion, since students have been using it only to chat about unrelated topics. Teachers are trying to help students use technology in appropriate ways, and see this addition as unnecessary and as yet another potential distraction that they have to help students manage. I don't question the fact that it might be useful in some realms, but in this case, it has no added value from a teacher's point of view.
