Don Box is pointed to the Lorem Ipsum page by Nikhil...

Hoax or not, many people use Lorem Ipsum text to keep people from being distracted by real text.  It's supposed to stop things like these in a graphic layout design session:

• A business stakeholder interrupting the session saying “those figures aren't right... Sam always produces more than one million sales per year!“..
• A user not listening to the demo because he's interested in the text you copy-pasted into the main content area from slashdot
• And other equally annoying interruptions / problems stemming from people not focusing on the purpose of the meeting / presentation, and instead being distracted by a trivial “space-filler“

So we use “Lorem ipsum dolor sit amet...” (see the page for further details). 

But beware!... True story - In demos to different groups of users of different products (but in the same company) that used Lorem Ipsum, a comment was shouted out - “Cool! - our new site will automatically translate text - look, they have it in french!” (or italian, and even one spanish).    This caused me to have to stop and explain that no, our site does not translate text - and then have to discuss the prioritization of that now critical feature. 

I now explain the “fake text“ used in the demo before showing a single screenshot.
