Blogging and content syndication course.
Blogs are software systems that allow you to easily post a series of documents to your website over time. Many people use blogs to display daily thoughts, rants, news stories, or pictures. If you run a blog, your readers can return to your site regularly to see the new content that you have posted. Before blogs came along, maintaining a website - and updating it regularly - was a relatively tedious process. Some might call blogging a social revolution! Now it's possible to add content from news agencies, other web sites and even other blogs using a technique called "content syndication." This course gives each student both the theoretical background and the hands-on experience for effective publishing using blogs and syndication.
