"Publishers and sites can pick and choose whatever data they want and create widgets with a customized local feed they can place in a sidebar. These could include Tweets about about the publisher’s business, Flickr photos, check-ins, or Yelp reviews. Widget publishers can also opt to include ads in the widgets targeted to the same location and content on their sites and split the revenues with fwix. Affiliate links to group buying deals is another source of revenue."
