Social network sites (SNSs) are bundles of information and communication tools that can be used to support collaboration, among other uses. In a qualitative study of adult Facebook users (N=18), we found that some users did turn to the site for information uses that are embedded in social activities, including organizing events, establishing online groups, and seeking information. We also discuss the features of Facebook that respondents discussed as being important to these uses.
