Stack Overflow, the very successful question and answer site for programmers, have now released their own API into public beta. The API actually works with all of the Stack Exchange sites, including serverfault.com and superuser.com, with more sites possibly launching in the future. The API is supported by the site http://stackapps.com.
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.
