first class of Udacity nanodegree is full?

When this sign up opened up more than a week ago ( and I was on their email list by request), I signed up by brief application immediately since their deadline was Sept 21 for application. Apparently they choose who they accept and then invite the first class ( total enrollment unknown). Their website now says that the Front End Web Developer is " at capacity" and to ask to be on the wait list. It is not clear whether this means they had a small internship class already and that is (was) full, or whether the new course is full. Also, there is no way to tell what the enrollment cap is, or long the wait is.

Could it be that massive numbers signed up so quickly, that the first nanodegree course offering was "full' in a day or so?

It all made me grumpy like there are so many people in the world that in 2 seconds, five million people sign up for the same thing. Cheez, this is like college admissions, or Kafka.

I googled industriously to catch any new news or explanation. Anybody heard anything about this? Did the thing open and shut like a mousetrap, accepting only the elite who responded in 30 seconds, staying up all night for an email to start applying?

Grump. I'm gonna go get some chocolate and inhale it.
