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.
With APIs becoming more and more prominent, a growing number of companies are finding success with API-only or API-centric offerings. So is building customer-facing applications a thing of the past? While there is good reason to believe that the trend toward API-focused companies will continue and even accelerate, there are still virtues to building end-to-end solutions.
