I am most intrigued by the annotation demo you showed, since annotation is painful to set up for small projects. Can you talk about it in more detail? Can I tell who the user is so I can have multiple annotators? Can I use gold data to determine which annotators aren't paying attention? Where do I learn more about how to build this kind of tool? Overall, kudos, I signed up for the waitlist.
