Techniques are described that facilitate generating useful content based on user interactions, such as by providing an answer-providing service that facilitates interactions between users who supply questions and users who supply responses to the questions of other users, as well as using the generated content in various ways. In some situations, some users of the answer-providing service are provided with pay-per-response functionality in which the user is allowed to elect on a per-question basis to include a paid response or other indicated information (e.g., advertisements) in an answer for a question in exchange for payment from the user, such as for use by merchants with questions that are related to products and/or services provided by the merchants.
