Bing Again is a new search engine that does something quite interesting for a change: it can look at the popularity of any given concept on Facebook in order to determine how high or low results should be positioned.
That makes some sense, if you think about it. Right now, the popularity of content on Facebook can be easily determined by looking at how many times any item has been liked. If people like something, then that must be because it holds some transcendence.
Additionally, all the main search categories (IE, Web, Videos, Images and News) become accessible at once when using Bing Again.
So, summing up: Bing Again mashes up Bing and Facebook. It fetches its results from Bing, and it orders them based on how relevant they are on Facebook. It is a fresh way to look for online information. And I am yet to mention that a bookmarklet is available for those who try Bing Again and find it really useful.
