  10. Why bother simplifying? • You lose visitors? • It just makes sense to do things right for your visitors • Think of Apple and where it got them by doing things easy to use • People “satisfice”* and they “feel good” when they get things right BUT • It is more important to make something work, then to make something simple enough * Satisficing + sufficing (see Chapter 2 in Don’t Make me Think)
