Need feedback on a product idea - Instant one-to-one chat for learners

We are currently working on a side project. I just thought that I should feedback from HN community before building it. Your feedback would be of great help to us in shaping the product. Our motivation for building this was generally people get stuck while learning online and lose interest because there is no one else to discuss, help him to get unstuck.

The idea is to build a platform where anyone can search for a keyword and instantly get connected to other learner, experienced person or an expert based on his needs. Then he can have a one-to-one chat (video, text, image) to speed up his learning. People who to help can sign up to help or advice for free or get some money. What do you think of such a platform? Would you use it? Why or why not? Please leave your feedback as a comment or fill this form http://goo.gl/forms/KWhLOeyzmr.

You feedback would be of great help in shaping our platform. Thank you.
