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.
