For all you people trying to get started with building your own uber-cool Social apps (connecting with Facebook, Twitter, LinkedIn, TripIt, etc.), Spring Social comes to your rescue!
After trying out a variety of tools and SDKs for building social applications, I have found this to be the best one to get yourself started within minutes, especially when combined with SpringSource Tools Suite, which provides a convenient development environment to build your applications. The project also comes with a set of ready-to-go samples and showcase, so that you get a clear picture of how to integrate with the most popular social networking websites of today.
So, get started now!!
