Google gather lots of profile information from you. You may be using Orkut, Blogger, Bookmarks, Chrome Bookmarks, notebook and other services provided by Google. Google wants to provide you a way to carry your data whenever you like in easy way and free of cost. They think the data is your and not of the products you use. So, Google do not believe in charging anything for this and Google also want the way to managing data by a users should be easy.
At the heart of this lies our strong commitment to an open web run on open standards.
A liberated product is one which has built-in features that make it easy (and free) to remove your data from the product in the event that you'd like to take it elsewhere.
Google has already librated Blogger data. You can import and export your blogger post very easily.
