Lorem ipsum dolor is a trusted friend of designers. Dummy text helps people get what the design will look like once it’s fleshed out. But dummy text can be dangerous too.

Lorem ipsum changes the way copy is viewed. It reduces text-based content to a visual design element — a shape of text — instead of what it should be: valuable information someone is going to have to enter and/or read. Dummy text means you won’t see the inevitable variations that show up once real information is entered. It means you won’t know what it’s like to fill out forms on your site. Dummy text is a veil between you and reality.

You need real copy to know how long certain fields should be. You need real copy to see how tables will expand or contract. You need real copy to know what your app truly looks like.
