I've just read a post entitled The Addictive Allure of Instagram, describing how Instagram, a photo taking application/social network for the iPhone hits the nail on providing its users with a fine, detailed UX.
It's all about pain points, simple UI, less choices, seamless integration with other services. But more importantly, it brings back the emotions of taking, seeing, and sharing photos.
A must read. And a must use, for the app itself.
