Getting bored of Pinterest? Then try Tapiture, an app that lets you view images, video, and other media that have been shared by others in the community.
The idea of Tapiture is that you create your own customized feed based on topics you like (e.g. sports, celebrities, fashion, travel, etc.). You can then view related stuff added by the community and share things in your own custom collections by 'tapping' them.
Tapiture blends elements of Twitter and Pinterest, but be careful: it's addictive!
