A technique for providing targeted information to users involves using demographic or specific user data. Each user may have some demographic data associated with them, which may be compared to, by way of example but not limitation, another user, a product, information, a location, or other goods or services. Promotions that take demographic information into account can be effective in presenting information to a user, which is more beneficial to both the user and a vendor or expert associated with the promotion. Specific user information can be used to address specific user needs.
