Facebook

link: http://www.facebook.com

Facebook is the most popular social networking site in the world, and as such it has to keep its design fresh and easy to use. While there is alot of freedom on this site, it's not as customisable as other sites I've posted, as it doesn't allow you to change the colour scheme or background, so everyone is stuck with the blue and white.

That's not to say it's a bad thing - the design is easy on the eyes and it's relatively easy to navigate. It's made easy to keep in touch with all your friends which is the main goal of the website.
