I love blockquotes. I find them so useful for pulling out blocks of text and creating interesting features within article content. But they're so much better when you style them with fancy styles. While it's possible to use generated content CSS to add the quotes to the front and back, this isn't reliable - IE doesn't like content inside of CSS. But this site shows how to create fancy blockquotes with visual quote marks using a CSS 3 property last-child. They also show you how to do it using content, but I don't recommend that if your site has a lot of IE visitors.
