The basic rule of the experience age

More features are not better; adding features does not make things easier; confusing users is the ultimate way to destroy a business; style matters; add a feature only when it can enhance user experience; any feature that requires learning will only attract a small segment of users; useless features are not just useless, they can ruin usability; users don't care about technology, they only want to know what the product can do for them; forget about key features, focus on the most critical user experience; simplicity is hard, so less is more.
