The article explores the role of digital media in supporting lifelong learning. In particular, it focuses on bloggers who write their blogs voluntarily in their own free time. The aim is to examine how lifelong learning--viewed as self-directed, nonformal learning and active participation that evolves from a desire for self-actualization--occurs in the processes of blogging. The data for this small-scale study were collected by qualitative email interviews. In all, 11 Finnish bloggers participated. The findings show that active participation, promoted and enabled by blogging, was actualized in both online and offline environments. It was embedded within six functions of their blogs that the bloggers mentioned: (1) learning and studying, (2) guidance and tutoring, (3) bringing new perspectives to public discussions, (4) applying expertise, (5) creating in one's own space and at one's own pace and (6) being part of a digital media culture. The findings indicate that blogging can promote nonformal, lifelong learning in many ways. Blogs and blogging constitute a learning environment that promotes active participation by making interesting, meaningful and enjoyable activities possible, and consequently the enthusiasm to actively learn and develop.
