I used wordpress to create a mockup of an auction platform for educators and learners. The inspiration for a site like this is to lean on what makes kickstarter and ebay and fiverr so compelling: a platform for a marketplace built to take advantage of more immediate supply and demand forces.
An educator can auction off the online tutorial of a subject they are interested in. They set a base bid for a number of spots for an online experience akin to a seminar or workshop. First time educators can only charge either free or small $5 dollar fee for their first offerings.
Students, looking to learn about particular subjects, can notify the service of their specific educational needs and wants. Educators can see those requests and taylor an experience based on that demand.
Students can then review the educator, rewarding them for good work. Those good reviews would lead to higher karma points which would give the tutor the ability to charge more for their services.
Instead of using the model of MOOC of taking small amount of product and scaling it, the scale would be on the order of how many educators and students there are, much like how scale in ebay is not on the number of buyers per product, but the number of auctions occurring.
