I can figure out some of the words, but I wouldn't really call that font "legible".

Edit: Well, apparently I didn't even realize it was the lyrics to Never gonna give you up. Tells you how hard to read the font is! Once you know it though, the font suddenly becomes much easier to read!

This really depends on your display being exactly the same type as the author's. I have to just about rub my laptop screen on my nose, but once I do that all the words are perfectly legible for me. (I don't mean pleasantly legible, but I can definitely read it.) If you look at Cleartype or font smoothing controls, you can see how many types of LCD monitors there have been.
