The PopURLs network made by Austrian entrepreneur Thomas Marban is a website that contains a lots of hot enterprise IT news. Hovering over items for a preview of the feeds from a long list of social news and media sites is a remarkably feature of this site.
By scrolling down of the page you can find new photos added to flickr and behance, videos from best popular vidcasting websites, news from best bloggers. In short, you'll find there many popular URLs, from the Wii to Facebook.
One of the other remarkably feature of this network is allowing to choose between the familiar classic or river view as well as the new cluster layout that groups content by topics rather than by sites.
The whole site is beautiful.
