Authorities in our business will tell in no uncertain terms that Lorem Ipsum is that huge, huge no no to forswear forever. Not so fast, I'd say, there are some redeeming factors in favor of greeking text, as its use is merely the symptom of a worse problem to take into consideration.
Anyway, you still use Lorem Ipsum and rightly so, as it will always have a place in the web workers toolbox, as things happen, not always the way you like it, not always in the preferred order.
