Agreed. You should only take the page rank with a pinch of salt. It gives you a very distorted story of what's going on with your website. Pay a lot more attention to the more specific details, such as what keywords and key phrases people are using from the SERPs. I think the biggest success you can have with a site is when you're absolutely happy with it, it's making you the money you intended it to do, and it's helping you fulfill your personal goals.
