A friend of mine, from fark.com, has sent me an image that helps the common user and surfer understand 2257 a little better. Its really explanitory and I think that all of us would benefit by helping surfers view this image.
So if you have a blog or a site that you feel could benefit from this graphic feel free to use it, he's given it 100% distribution rights for all webmasters who wish to pass it along.
