You may have carefully crafted a Pinterest board to plan your dream vacation, but how are you going to make that trip a reality? Pinterest thinks it can help. The social site has launched an app developer platform that lets you take action based on your boards and individual pins. You could book an itinerary in a travel app based on your pinned destinations, for instance, or create a dinner board based on recipes in a cooking app. The platform is in a US-only beta phase at the moment, so it could be a while before you're using Pinterest-savvy apps. However, it could be worth the wait if you've spent more time yearning for pinned goods than getting them.
