Simplicity-wise, tumblr does a pretty good job. Facebook is also quite slick And FML also has a very nice, rounded and clean style. If you ask me, the thing people look out for the most in websites is elegance, and something artsy. Light colours are easy on the eyes, as are rounded curves (of course, you want things in moderation. Get too rounded, and the site just gets messy). Also, with all this newfangled technology stuff, something which is cool, modern, hip and seamless works wonders. This is why I like websites like Facebook. When you click on a box, the application just slides into view, as opposed to opening itself on a new page. A wall of text is jagged, boring and hard on the eyes (black against white is so nineties). In fact, for inspiration, why don’t you just check out this site? Part of the reason why I love it is because of the very slick web design.
