The Youth Digital Hub (YDH) is a prominent center of digital information designed to effectively support the Youth Community of Practice (YCoP) by providing them with timely and relevant information. However, there is a lack of discussion on the best practices regarding a conceptual system model that can successfully and efficiently support YDH, particularly in the context of Web 2.0 applications. This paper addresses this gap by presenting a conceptual system model for YDH, utilizing Web 2.0 technology as the application platform, and incorporating both the system's functionality and non-functionality. By employing the latest comprehensive literature analysis and secondary data, this study aims to outline the model and ensure its successful and comprehensive operation to support the YCoP. Additionally, the paper discusses various challenges and issues that need to be considered to optimize the effectiveness and significance of this youth digital hub.
