Millions of people visit the Web every day. Many companies have found ways to personalize their interfaces with individual customers. Visit Web sites of your choice that offer such personalization and report on the products or features you find. For instance, Web portals like MSN and Google let users customize the home page to fit their personal needs. Other e-commerce specialize in customers ordering one-of-a-kind items that have been personalized for them with their own photos and/or text. Investigate how retailers can offer these kinds of services and the benefits to the business (how can they just sell one and make profits). Think about photobooks, coffee mugs, mouse pads, etc. Please make sure you're analyzing a personalized e-commerce site.
