I have a problem with their team not being fully public. But I have asked them so many questions and they have always been there for me. They know stuff.
More transparency regarding the teams identities would be welcome. The days of the anonymous developer are pretty much over since every credible project has people's real names. I think this is a credible project but having psuedonyms for the team members makes it look far less so. This is especially true since presumably the instructors will be vetted and won't be hiding behind psuedonyms.
