Stack Exchange is a fast-growing network of 176 question and answer sites on diverse topics from software programming to cooking to photography and gaming. Non-programming questions about the StackExchange itself should be asked on meta.stackexchange.com instead.
The Stack Exchange Network (also called StackExchange) is a group of question and answer websites on topics in many different fields, each website covering a specific topic, where questions, answers, and users are subject to a reputation award process. The websites are modeled after Stack Overflow, a forum for computer programming questions that was the original website in this network. The reputation system is designed to allow the websites to be self-moderating.
