This website is very big in the Rubik's Cube community. It is a website dedicated to the optimum solutions of Rubik's Cube, and is a very good source if you are looking for the mathematics behind solving the Rubik's Cube. It is one of the sources I used for the final algorithm this website uses. The Cube Explorer will solve a cube in fewer moves then my website, at the expense of longer compute time.
A site dedicated to news, competitions, etc... of the speed cubing phenomenon.
A site tailored to everyone to explain how to solve the Rubiks Cube the proper way.
