What makes an effective website?

Beautiful and neat design, categorizing each topic in a fabulous coloured box. Avoidance of boring topics, always talking about concerned topics with respect. A very soft beep on a mouse click, avoidance of routine found at every website. Do not include the ordinary flash adv that comes at every website, including chat room's striking games, horoscopes , and to receive the others opinion in a definite topic that makes the others interested in the website...
