Like any Drupal themer, I've done my share of grumbling about the frequently ridiculous level of nested divs with dozens of classes. I'd heard some people mention a module called Semantic Views, but I never really understood what it was for until I found this video. If you don't understand what the big deal is either, take the four minutes to watch. It's a total "ah-ha!" moment. I'm happy to say that I just used Semantic Views for the first time on a client site, and it's just as awesome as everyone says. It saved me a ton of work and let me get exactly the markup I wanted, even while working around Chuck's nested views.
