"CourseTalk is what you might expect - an early stage Yelp for MOOCs - a place for students to share their experiences with these courses and a way to discover new courses they'd enjoy. Given that it's still nascent, the platform's design is simple and its user experience is straightforward: Visitors can use the general search bar which is front and center, or peruse through "Top Rated," "Popular" and "Upcoming" verticals, or search by category, like Business, Computer Science, etc."
The open-source educational marketplace will give everyone access to the best universities in the world. This will inevitably spell disaster for colleges and universities that are perceived as second rate. Likewise, the most popular professors will enjoy massive influence as they teach vast global courses with registrants numbering in the hundreds of thousands (even though "most popular" may well equate to most entertaining rather than to most rigorous).
