The term "Product Designer" is one that suits the web well. In my opinion a product designer should be able to create visually appealing designs that are usable. They should have an understanding of user experience and HCI issues - but not necessarily be an expert or have a PhD in the fields. They should be able to prototype their designs in HTML, CSS, and JavaScript and do some minor back end coding to get things working (they don't necessarily have to do this all the time, but they should have the ability to do so). FWIW, this is what Facebook's product design team does (from my understanding of it, anyway)
