People are getting used to subscribing to RSS feeds (an easy way of keeping track of changes to your favourite websites) from websites and blogs as a way to keep in touch with new content and headlines. The trick with RSS is that the news comes to the user in their feed reader, rather than them having to visit each side separately. So make sure your site is putting out RSS feeds - most content management systems will do this as a standard feature, and all blog services will have RSS feeds.
If you use something else for your website, you may need some technical help to add them by hand. RSS is also a way to syndicate your content to other sites, allowing them to easily pull in your headlines, which is a good way to promote your content automatically and have it appear on their site as featured content. Other sites use RSS to aggregate news making it easy for people to keep up with the issues that interest them. Think about how you can make your information or data shareable and make it available through RSS so that others can use it for mash-ups, where people take data from two or more sources and combine them in a way that adds something new, like these examples from Kenya and Zimbabwe.
