Pull Quotes with HTML5 and CSS

A pull quote is a typographical technique in which an excerpt or quote from an article is duplicated within the article using a different formatting style so that it jumps out at the reader.

Blatantly copying the excerpt of the pull quote into it’s own element is not the way to go. A pull quote is a purely visual technique, and therefore should not change the structure of the body. Next to that, a structural representation of the excerpt would be seen twice by people using feed readers or services like Instapaper, as well as be re-read for people who use screen readers. So how can we best author this into our mark-up?
