When e-learning initiatives from developed countries expand or establish an initiative in developing countries, knowledge needs to be transferred. This paper shows that developing countries still are lagging behind in the use of social software within learning environments. But this could be easily overcome, nowadays, by implementing open-source tools or simply using Web-based free services and well-directed training on teachers. This paper also points towards benefits and possible barriers of using social software because barriers can limit or even prevent the knowledge sharing process.enText/Conference Paper1617-5468
