Originally, my interest in user interface design came from the poor design of websites. Back then, websites had poor designs (even poorer than nowadays) and were hard to navigate. Every website has its own method to deal with the problems of limited screen real estate and too much functionality. A nice example of a good way to do this is Google. The products and possibilities they offer keep growing, but the complexity of their products has been stripped down to a minimum. A nice example of this is their main page, where there are two buttons and a menu bar. The design of their menu bar has been based on a swiss army knife, take out what you need, everything opens in a new tab, and whenever you are done using it, put it back again. I think this is a good example of a design of a big complex website.
