Angie's List: Is It Working for You?

We've mentioned Angie's List as a referral site for contractors, designers and tradespeople but we want to know from you if you've found success using this service and would recommend it to others? They seem to have made a few changes lately and are pumping money into marketing but should we all be jumping in and trusting their findings? Or should we just rely on our own due diligence when it comes to hiring a contractor?
