Web design is simpler than ever, and that's a good thing. web 2.0 design means focused, clean and simple design that is all about the content.
There are two important aspects to achieving success with simplicity:
Whenever you're designing, take it as a discipline consciously to remove all unnecessary visual elements.
Concentrate particularly on areas of the layout that are less relevant to the purpose of a page, because visual activity in these areas will distract attention from the key content and navigation.
Use visual detail - whether lines, words, shapes, colour - to communicate the relevant information, not just to decorate.
