I’m not sure this app checks the boxes for me. If students want to ridicule each other they will do so regardless of circumstance – whether face-to-face or over an annonymous service like YikYak. This app doesn’t add anything new, and students can and do already make groups to discuss course questions. Even back when I was in university the first time (2002) we had Rate My Professors to discuss their classes and performance. These fellows seem well positioned (personal and business connections, previous experience) to create something of greater use than this product, but their current team isn’t made up of proven innovators, so it may be difficult compared to other ventures discussed here.
