BBK, Dun kno'
Any recommendations of books there? Is it worth? :)
the "Pay $15 or More" tier alone is a steal, just for About Face: The Essentials of Interaction Design and Designing for the Digital Age: How to Create Human-Centered Products and Services. I'm not familiar with any of the other books though.
I was gonna just say the same: About face alone makes the whole thing worth it
