Agreed, this seems to be written as marketing first, education second. Good content marketing puts the priority on learning first. If the Bit folks are reading this and interested in improving, I suggest reading Kathy Sierra's book and watching her talks.

This article doesn't mention Kathy Sierra, but as someone who has worked on User Onboard with Samuel, I know he'd want to give her some of the credit.
