The idea behind the name is that rather than just tutoring generally (which is provided by sites like wyzant), these tutors are specially selected for their competence with certain MOOCs - they've taken these courses before, typically as a student in a university. The "u" represents the learner - while MOOCs are a depersonalized learning medium, this service puts "u" back into it. We don't offer MOOCs, but a service used parallel to taking a MOOC to enhance the student's likelihood of success.

I think you misunderstand - it's designed for use alongside a MOOC, for people who want to pay for personalised help in completing the MOOC. It's not a MOOC platform itself.
