Startup Idea : Random knowledge chats

It’s hard to learn cool topics directly from experts (unless you listen to a podcast, which is not very interactive).
My favorite feature on Wikipedia is the “random article” button, which sends you to a random Wikipedia page. This company would take this same idea and similar to Omegle places you in a random 1:1 video conversation for 15 minute conversations for $5 each. The platform would allow you to learn random things from random people who are an expert in their subject and all you would have to do is pay them with coffee/tea/pastries. Perhaps it could be called, Teach for a Coffee. Get rated after the end of each interaction and become more of an expert. Perhaps, eventually, the platform would create partnerships with media companies to give people a foot-in-the-door to become talking heads on programs like CNN, Fox, MSNBC, and more.
