Crystalcat on Nibbler

A pet love of mine is Nibbler. I adore this site because it gives a good, general overview of all aspects of optimization.

I am currently ranked 1st in South Africa (nibbler.silktide.com/u/xxcrystalcat) with only three websites listed.  Best practices are encouraged here, which hold an important stake in not only optimization, but SEO as well.
