Design Stack Overflow

Stack Overflow is one of the largest online communities for developers to learn and share their knowledge. The website provides a platform for its users to ask and answer questions, and through membership and active participation, to vote questions and answers up or down.

Users of Stack Overflow can earn reputation points and badges. For example, a person is awarded ten reputation points for receiving an "up" vote on an answer and five points for the "up" vote of a question
