Whilst the role of online communities (OCs) in knowledge exchange and generation has been widely discussed, limited research exists on the distance and direction of OC knowledge flows. In this paper, we examine this issue by taking the case of an industry-founded OC that rendered around the use of a specific ERP module used by public sector organisations. Through a grounded analysis approach, we extend literature on OCs by identifying user-generated practices that enable knowledge flows in the online space as well as by examining the travels of these knowledge flows taking particular account of the distance they cover and the direction they take. Findings point to within, outwards and inwards travels of OC-related knowledge flows showing a widely spread OC knowledge impact. The theoretical and practical implications of the study are discussed.
