Paying attention to the little details, the ones that no one might ever notice, is a great way to take pride in your craft. When those details DO get noticed, you will show your customers and users that you care. Plus they are a great way to add character and show some personality in your apps. Through Mike Champion, I found this great tumblr blog called Little Big Details which has a great collection of such details. A great site to get inspired and know that those little big details do get noticed.
