Since the emergence of Web 2.0, the idea of online knowledge sharing has been gaining attention of researchers and online communi- ties. We can observe the popularity of such services on Wikipedia and numerous Q&A systems, in which ordinary users can explicitly ask ques- tions and provide answers thus raise their expertise level by learning from others. Users dynamically switch between roles of content producer and content consumer. This paper applies game-theoretic approach to study how different community member profiles and reputation can af- fect the learning process and, in consequence, credibility of the provided information.
