Forms (digital and physical) are always the orphans of information design.
“Though some decry flat user interfaces as pure fashion, or the obvious response to skeuomorphic trends, many designers have embraced the flat approach because the reduction in visual styling (such as gradients, drop shadows, and borders) creates interfaces that seem simpler and cleaner. The problem is that most flat UIs are built with a focus on the provision of content, with transactional components (i.e. forms) receiving very little attention. What happens when flat and forms collide? User experiences can, and often do, suffer.”
