Maybe it's because they refuse to use Lorem Ipsum in their mockups http://www.pragmaticmarketing.com/publications/magazine/6/4/...

"There is no “Lorem Ipsum” used as filler for content, either. At least one of the senior managers refuses to look at any mockups that contain such “Greek” filler. Doing this detailed mockup removes all ambiguity—everyone knows and can see and critique how the final product looks. It also means you will not encounter interpretative changes by the designer or engineer after the review, as they are filling in the content—something I have seen happen time and time again. Ultimately, it means no one can feign surprise when they see the real thing."

Update: Just a clarification, I was being sarcastic. I'm a user and love the app.
