Blogging has grown exponentially on the Internet; however, the role of blogs within the enterprise remains ambiguous. Why and how do individuals use internal corporate blogs? What results do both individuals and the corporation realize from internal blogs? Our exploratory study of a large global IT corporation?s internal blogging system analyzed usage statistics, interviews, and the results of an anonymous, web-based survey. We found that benefits to users were social as well as informational, and that connecting with their community was an important value sought by all types of users. Heavy users of the system realized the greatest benefits, but they also constituted the core of an online community that provided important benefits to medium users as well.
