Any UI/UX needs to be effective (you can accomplish what it sets out to do, i.e, sell product, or find relevant search results, or write a letter, etc.) and be efficient (takes the least amount of effort to complete the task).

UX is a chasm

Crossing the Chasm

• Enhanced Navigation
• Trees, breadcrumbs, Hnav, Lnav, etc.
• New, intuitive approaches (Tafiti)
• Improved Dialog Style
• making your dialog boxes work (no cryptic error text)
• Mental Modeling
• If it's a shopping cart, follow the cart model, etc.
• What's the model of your site?
• Clever Visualization
• Intuitive UI
• Adaptive UI
• Follow the tag-cloud concept wherein more relevant stuff is bigger
• Frequently used buttons are bigger (or should the less frequent ones be bigger to encourage you to use them?)
• animation and scaling look cool, but after the initial impression can make your application/site seem slow (animations take time to execute, right?), so the more you use them, they should take less time, AND scale less as well (until eventually they don't animate/scale at all)
