I think it is a new approach to solving a broader problem, which is how do you gather the knowledge of a group of people efficiently. Sure, Tpstry is built using cool technologies (Rails, Mongodb), but using an interview process to gather structured data is what I find most interesting. We've built Tpstry to modify the interview questions based on previous answers. So new lines of questions are opened and others are closed. This helps with the user experience because it only presents the user with relevant questions.
