Pinspiration: A Social Network Based Around Photos
"Pinspiration is the best way to browse and post to Pinterest on your Windows phone. Think of Pinterest as a virtual pinboard - a place to catalog and share the things you love."
Pinspiration is a social network app that allows users to browse and share favorite photos. If you find a photographer you like, you can elect to follow that user and subscribe to their new pins. If you pin the app to the home screen, the Live Tile will rotate through the most popular photos that are currently being shared.
Pinspiration is available in the Marketplace. There is a paid version with full access and an ad supported one. Give the free version a spin here.
