For over a year developers have been asking for an API from Quora, the Q&A site that has recently exploded in popularity. The company had been waiting until there were "enough users and content on Quora." A browser extension outed the interface and now there is an officially released, but still alpha Quora API.
For snap-happy smartphone and tablet users, having somewhere to store their treasured pics is probably very appealing. Photo books have been a trendy favourite for a while now, and Printzel is an app-powered platform that allows users to create their own printed photo books directly from their mobile and tablet devices. The company also provides the Printzel API that now makes it possible for developers to offer printed books from their own applications.
