I really like blog posts that give a behind the scenes for design changes. I’ve just written an internal post for my work on the reasoning I’ve made changes to a key part of our user experience.
This is an interesting look at the effect of a new icon design for Foodnoms has increased downloads. I wish more developers and designers would be this transparent about their work. It’s great evidence that shows how important the users are in our design considerations. No matter how well you know your users you don’t know what’s the most effective design until you speak to them.
