It makes sense when you don't read everything, when you're reading a newspaper or a magazine for example and only read the articles that catch your attention.

It makes sense when you don't read everything, when you're reading a newspaper or a magazine for example and only read the articles that catch your attention. I really don't see how it makes sense in the context of a single article though. If I'm already clearly reading an article, a pull quote is only going to distract me.
