Masters thesis on social software, or more specifically groupblogs, wikis and social bookmarking and how they support knowledge management and communities of practice
gnizr is an open source application for social bookmarking and web mashup. It is easy to use gnizr to create a personalized del.icio.us-like portal for a group of friends and colleagues to store, classify and share information, and to mash-it-up with information about location.
Image Matters LLC contributed gnizr to the Open Source community, and continues to support its development as part of its gnizr Enterprise software.
