A media company on the Internet requires a lot of traffic to make it worth the time to make large-scale brand advertising happen, explains SlideShare CTO Jonathan Boutelle. His cofounder Rashmi Sinha said it’s important for a Web site to make clear to their users how they intend to generate revenue and whether it’s going to be through ads. Even when the site first launched, she continued, they have always had advertising. Sinha describes it as making a pact early on with their users that SlideShare will be an ad-driven service that they can use for free.
