Creating this documentation comes at a considerable cost and effort. And after all this effort much documentation is rarely consulted. API documentation is especially difficult to create: as just a few writers must create documentation that teaches concepts and that maximally covers the many ways the thousands to millions of developers may be using their API. Now, the trend may shift even more to indirectly documenting APIs themselves through a process called crowd documentation, by publishing blog posts and curating questions and answers about APIs. In this small study, we find various facts regarding Stack Overflow, including suggesting that developers may be getting as much as 50% of their documentation from the site."
