It's 2014 guys, not 80s or something. No-one needs to be forced by the author to read black texts over white background. Using memes, which are the most popular way of expressing feelings nowadays, is a good way to keep reader focused on the content without boring them bunch of new or uncommon stuff. If that was about php/mysql article, "adamors" might be right but this is a piece of information that we can call "priceless". So, enjoy and go try even if you fail.
