The whole premise of this post is built on a myth! Where is the evidence that darker colours 'are easier on the eyes'? Conversely, there are reams and reams of published data proving conclusively that dark text on a light background is not only far easier to read (because it IS easier on the eyes) but it also GREATLY enhances comprehension! Is it just a coincidence that your post complies with the PROVEN facts? Why not try publishing it using white text on a black background and watch as 'would be' readers quit trying after the first couple of sentences. Seriously, this is a case of someone thinking he/she had a good idea and that if he/she tells enough people it will come true. It won't.
