Simply explained weblogs are personal "diary-like-format" web sites enabled by easy to use tools and open for everyone to read. There is a growing cluster of knowledge weblogs used by professionals as personal knowledge repositories, learning journals or networking instruments (see Efimova, 2003a; Efimova & Fiedler, 2004 for more details). Used in this context, weblogs address personal needs of a knowledge worker, but they also create an opportunity for others to benefit from having emergent ideas and personal notes captured in public spaces instead of private collections.

The term knowledge work has been used for decades, but to date there is not much understanding what knowledge workers do and how this work can be improved. This paper contributes to the development of our theoretical understanding of knowledge work by exploring use of weblogs for professional purposes: as personal knowledge repositories, learning journals or networking instruments. We draw on the results of a weblog adoption study to explore knowledge worker activities and to propose a framework for analysing knowledge work.
