Nook isn’t doing that well for itself these days, but the Barnes & Noble subsidiary isn’t giving up. In fact, it’s pushing for more content than ever before to establish itself as a viable competitor in the cheap tablet space.

Nook announced today that Pinterest is now available on Nook HD, Nook HD+, Nook Tablet and Nook Color devices. The app is available from the Nook store, but it will also come preloaded with any new Nook device sold.

“Pinterest has long been one of our most requested apps and we are thrilled to bring it to Nook, along with the Twitter and Facebook for NOOK apps,” said Claudia Romanini, Vice President of Nook Apps, Nook Media LLC. “Our goal is to bring Nook users the very best in social media and these apps will bring to life the rich sharing experiences that Pinterest, Facebook and Twitter offer.”

Alongside Pinterest, Facebook and Twitter will also come preloaded on all new Nook devices. The Facebook app received an update that overhauls the experience to mimic what users expect out of a Facebook app on other mobile devices. With the new app, users can “see what their friends are up to, share updates, photos and videos, chat and have group conversations, play games and much more.”

The addition of Pinterest is just the latest move from Nook to make its platform more desirable to consumers. It recently launched Nook Press, a new version of Barnes & Noble’s popular PubIt! platform that allows independent authors to self-publish their titles on Nook. If it takes off, we could see Nook devices starting to sell well again as people clamor for exclusive content from up-and-coming authors.
