It is not clear, however, how much of work blogging is work-related versus social, or when work blogging takes place. In this poster, we present results from our examination of the temporal aspects of blogging within a large internal corporate blogging community. We compared our findings to similar analyses of employee email use and to college student Facebook use. We found that blog posting is temporally similar to email, while blog reading is more similar to Facebook messaging. Our results suggest that participation is both work-related and social, indicating a desire to connect to coworkers at multiple levels. To appear at CSCW 2008.

We have analyzed the fully anonymized headers of 362 million messages exchanged by 4.2 million users of Facebook, an online social network of college students, during a 26 month interval. The data reveal a number of strong daily and weekly regularities which provide insights into the time use of college studen s and their social lives, including seasonal variations. We also examined how factors such as school affiliation and informal online "friend" lists affect the observed behavior and temporal patterns. Finally, we show that Facebook users appear to be clustered by school with respect to their temporal messaging patterns. Full citation: Scott A. Golder, Dennis Wilkinson and Bernardo A. Huberman.
