“Flat design is nothing but simplicity put into practice. The fact that simple shapes such as rectangles and circles are being preferred over gradients and drop shadows shows that the tide is in favor of simplicity.”
Flat design done wrong
“Unfortunately, too many flat designs focused solely on the flat and skipped the part about fundamental design principles.”
(Steven Bradley Glicksman a.k.a. @vangogh ~ Vanseo design)
Flat or skeuomorphic is the wrong question: It’s about satisfaction
“The point of this process is to determine what style appropriately conveys the attitude and personality of the app itself. The intended impacts of each theme are not mutually exclusive – in fact, the hybrid direction we ultimately recommended deliberately borrows meaningful aspects of each.”
