Not to go all "land of milk and honey" on you guys, but the consumer is the biggest winner here. Naturally businesses benefit immensely as well, but the more we optimize with people in mind the more likely their needs will be fulfilled and consequently, the more likely we are to get those people to convert. Including people throughout the process and making the core goal to encourage them to do something ultimately makes the web a better place because everything we create will have a distinct purpose for the user and never solely for search engines. This is not to say we are circumventing the technical tenets of SEO as they are the price of admission.
