Wow, came here to find this ability doesn't exist. Amazed at how ridiculous this is. As a premium user, I share a ton of different notes with my wife and co-workers, and create new ones constantly. A shared stack (which is just a folder as far as I can tell), would make life insanely easy, but this doesn't seem to be happening. There are so many interface oddities in the desktop app already (e.g., not being able to drag notes between stacks on the left column), that I think I am going to start looking at alternatives - my general take is that Evernote is more interested in the feature checklist rather than usability and the roadmap forward, as far as anyone knows, is more of the same. Please prove me wrong.
