“Many articles have been written on what is probably the single most ubiquitous interface element within Web applications today: the form. Forms justifiably get a lot of attention because their design is critical to successfully gathering input from users. Registration forms are the gatekeepers to community membership. Checkout forms are how eCommerce vendors close deals. But what goes in must eventually come out, and the information users provide to Web applications often makes its way back to users in the form of tabular data” (Luke Wroblewski – UXmatters)
