Let's face it, keeping a website's content fresh and up to date can become a world of pain. Your client might want a website to have daily content that is both interesting and entertaining but, in reality, they will only have time to update it two or three times a week.
An easy way around this is to hook up an RSS feed into the Flash site. RSS ('really simple syndication' or 'rich site summary' - depending on what you believe) takes the form of dynamically updated feeds, which are available on thousands of websites. From news to sports to podcasts via special-interest subjects, you'll find something that fits the site.
