This sound like a great project, and it seems like a natural fit here on the Steem blockchain! I hope this can potentially be something that even attracts new users to sign up to the blockchain, because who would not want to get some dollars for answering questions about stuff they are knowledgeable about?
I will definitely try out the platform today, but I don't have any other key than the Posting one attached to this computer, so it will have to be later.
