Experty is a project for education, but slightly different from most projects in this area. It really removes the need for intermediaries, creates a decentralized system. This works just like Uber only for education, connecting teachers and students, using a rating system in order to motivate both sides to make maximum efforts. At the same time, the payments are automated with smart contracts to simplify and secure the whole process. So the blockchain application in that case seems reasonable. But, it's bad that the project does not yet have a working product.
