Danogo Answers is a community-driven knowledge market website that allows users to ask questions of other users and answer other users' questions. Virtually any question is allowed, except ones that violate the community guidelines. To encourage good answers, helpful participants are occasionally featured on the Danogo blog page. Though the service itself is free, the content of answers are owned by the respective users—while Danogo maintains a non-exclusive royalty-free worldwide right to publish the information.

Free knowledge markets use an alternative model treating knowledge as a public good.  Danogo Answers is just like Knowledge iN, Yahoo Answers, Windows Live QnA, Ask Metafilter, Wikipedia:Reference Desk, Google Questions and Answers and several other websites that currently use the free knowledge exchange model.
