StackOverflow is neither encyclopedia, forum, nor blog, but rather a combination of all three that is specifically designed for programmers and developers. It’s a community for programmers to answer and ask programming related questions, a place where developers can vote on most useful answers, and an encyclopedic resource for thousands of techies to troubleshoot their problems. The site is completely built upon user contributions and currently boasts 1.2 million users, 6.6 million answers, and 13 million comments.
