More sound advice…

In Gimmicks and Patterns I wrote that new features either become table stakes, or are dismissed as being gimmicky. As some readers noted, this is a simplification of what happens. The Kano model shows exactly how the slide happens, and explains why any one particular feature or trait will never be a sustainable advantage. Here’s how it works… When new features emerge, even the smallest investment in them delights users as they are novel. Take “Location” for example. even a tiny investment, such as defaulting country and timezone correctly impresses users. As you invest further you really begin to delight them.
