Behind the myths of citizen participation: Identifying sustainability factors of hyper-local information systems

<jats:p>Various information systems have emerged to facilitate citizen participation in the life of their communities. However, there is a lack of robust understanding of what enables the sustainability of such systems. This work introduces a framework to identify and analyze various factors that influence the sustainability of “hyper-local” information systems. Using longitudinal observations of participation from 35 online neighborhood discussion forums over six years, we analyze the relationship between sustainability and online–offline community characteristics. Our results not only show patterns consistent with previous observations but reveal the dubious influences of member heterogeneity and network structure. Design insights are discussed.</jats:p>
