One simple widget example is National Geographic's "Photo of the Day" widget for Facebook. The Windy Citizen, an independent news site in Chicago, has a widget for adding their news feed to a social network or blog. (Scroll down to the section on "Add today's top stories to your site" to see it.) The New York Times also has a lot of different widgets you can build from news on their site.
