The research goal of this study was to investigate how website design quality and website service quality affect participation behavior in the online travel community by moderating tacit knowledge and commitment.The design of the questionnaire linked it to the invitation message on the three travel communities, of which 235 were returned completed. The finding of the study shows that an online travel community that allows quick manipulation capabilities is likely to attract its members. To succeed, online travel communities have to rethink the way in which they embrace a new art of dialog and collaboration with their members. Copyright © 2012 John Wiley & Sons, Ltd.
