The Consumerist is a resource blog that appeals to the consumer in all of us. It posts links, articles, and announcements that have anything to do with saving money or getting a fair deal as a customer.
Their material is a little more "aggressive" than a personal finance blog, but it can be very helpful. I am most interested in their "Confessions of..." series's. For instance, there is a "Confessions of a [insert cell phone company] Salesman" for virtually every major cellular service provider. Articles like these give valuable insight to keep from getting taken advantage of, etc. There is an abundance of content added daily, so there's plenty to keep you busy here if you enjoy what it has to offer.
