The syndicated content always includes titles, also known as headlines, for the newest published stories.  Each headline acts as a direct link to the stories on the remote site. Along with the headline, most sites typically provide either the first few paragraphs of the story or a short summary. Many individuals use client-based news aggregators on their personal computer to aggregate content, such as %amphetadesk</p>";
