Hi all experts! We have recently launched www.kagoon.com , which operates in the arena of directory tagging. It allows users to build a taxonomy in a collaborative way, and associate paragraphs from documents or from web sites to branches in the tree. Thus, for each tree branch (represents a long tail topic) you get many quotes from documents/webpage, and you get to save time of reading long documents/pages just to find 1 paragraph that is relevant. Another advantage is that kagoon keeps full track of all actions committed by users, to be able to undo when necessary. Any criticism is welcomed The Kmaster.
