The Newsfeed box is completely customisable. This is evident if you visit all the sites listed below. Each Webmaster has customised the Newsfeed box to make it fit in with the feel and look of their own site. Customisation is done through CSS which can change the style of font-family, font-size, font-color, background-color, border-style, border-color (if any), and overall size of the newsfeed box. If you're familiar with CSS you can have a field day.
Only a few lines of code are required to display the Newsfeed box on your web page. You do not need to be able to run any fancy scripts from your hosting server.
