In this paper, we explore the popularity of contents at social curation sites. More specifically, we evaluate an article’s popularity at a given point in time and enduring popularity. The results of analyses demonstrate that the amount of content in an article and the initial page views positively affect the page’s popularity. However, an excess amount of content has a negative effect on outbound traffic. Finally, we find that a within-site bookmark prolongs the life of an article.
