I think, as a kind of "get an explanation for a specific thing" this is a fantastic addition to the world of teaching/tutoring and hope it succeeds. I tutor my son in engineering level subjects some times, but I find that I need tutoring myself too to understand some of the things :-). There are various well-known homework-help sites where you can post questions and get answers from "experts", but, none that I know that use a video based approach for the response. As an aside I think we need more videos that explain how to approach solving specific types of problems -- not just the answer, but how to tackle breaking down the question and what to look for in the question to decide what theoretical aspects apply to solving the problem. I guess once a person has sufficient theoretical knowledge, they get an intuitive understanding how to do this, but engineering coursework doesn't leave too much time to digest a subject in depth and any help provided to minimize the time to internalize concepts/insights is always good.
