Then I was researching information about the Connections series online and accidentally stumbled on a link to KnowledgeWeb. I was amazed to learn that such project already exist, because I dreamed about something like it for a long time. I am extremely interested in the development of science and technology (goes in the family, my father's doctoral thesis was done in this field) and was envisioning a tool similar to K-Web for a long time. Now I found it. :) Have to find whether it's actually useful (i.e. if custom content can be added there).
