My co-worker Nick Bradbury (FeedDemon developer) posted an interesting series about app design and development called “Simplicity Ain’t So Simple.” (He can say “ain’t” because he lives in Tennessee. ;)

It’s in several parts: Part 1, Part 2, Part 3, Part 4, Part 5, and Part 6.

(Nick’s a Windows developer, but he often thinks like a Mac developer.)
