What a missed opportunity. The author could have talked about broader design trends like skeumorphism, linked Apple's design language to what peers were doing at the time, and have delved into design detours and dead ends such as Apple Copland, which influenced subsequent generations of icon design.
The vibrant custom icon culture of the 1990s and early 2000s is also not discussed.
Instead, we are given a context-free post comprised of pretty but disjointed visuals.
Rather than complaining on the internet to an RSS report bot, I will write the post as it should have been written (I have an enormous library of classic icons from the pre-Mac OS X period).
