Methods and systems for identifying, compensating and communicating with persons who have knowledge of, interest in, or experience with, products and/or services provided by an advertiser or marketer. In one aspect, a system includes a server to receive and maintain user information, including contact information and specified categories of products that are of interest to the user. In addition, the system enables an advertiser to search the user information to identify users who have expressed an interest in a particular category of product. Moreover, the system facilitates establishing connections between advertisers, and customers, while tracking the length of such a connection.
