This letter is a rejoinder to Xiang, Fesenmaier, and Werthner (2020), who responded to our letter to the editor about knowledge creation in information technology and tourism (ITT) research (Cai and McKenna 2020). We believe the authors have misinterpreted our claims and failed to address our main points in relation to the lack of theoretical and methodological development of ITT. Therefore, we address and clarify some misunderstandings in their response. We also elaborate on our ideas for broadening the paradigmatic boundaries of ITT research and opening up potential topics to tackle wider social issues. In addition, we provide more guidance for the growth and development of ITT through broadening boundaries, methodology and theorizing, as well as knowledge dissemination.
