The first is the addition of an image tab to the top of Digg’s main categories.
With this addition, Digg has changed how their taxonomy works. Now you can submit news, images, or videos to any category within Digg. So now you can view only sport images by clicking on images and then the sports category.
In addition, Digg broke out the “Offbeat” category on its own. And they have added a new “Lifestyle” category with sub-topics for “Autos, Food & Drink, and Travel.”
They also added a new image crawler to help index up to 10 images per article. Plus, they added an “Image Detection” feature that is displayed in a mosaic view to help sort and filter duplicate images from being displayed.
