I've got an email with a tip of a pretty useful web service called ScoopWeb.
ScoopWeb is a Real-time topic explorer, where you can enter a topic title and instantly get related digital contents from multiple sources (e.g. Wikipedia, Youtube, Twitter, Facebook, Flickr, Books, Newspapers, Magazines) all at once.
In Short, you can access the freshest information and multimedia content about almost any subject, person, place or event in one single place.
I think it can be very useful when you want information of some hot news that happens just now.
