Websites can sell.
They are particularly good at selling things that benefit from conveying highly targeted information. That is to say, generally at least, websites are good at getting information to the people who are interested in it. They arrive at your site as a result of consciously following links. By getting your sales message to people who are interested you have a leg up over those who broadcast to a predominantly disinterested audience. Actually I'm thinking more than a resume - you can use the web to actively market your skills online.
