I thought this was pretty annoying, actually. I was used to Coursera already, but had to create new logins, etc. Then I was confused because Coursera listed (and still lists) the DB course as coming soon at the same time leading up to the Class2Go version. :-( I'm slightly disappointed by the muddled way it was carried out.

Yup. Both Berkeley and Stanford -- Coursera's first schools -- are fleeing for the hills.
