Just got this invitation to download and join a new collaborative service for searching, exchanging and sharing information from Laurent Querel CTO at Yoono.
According to Laurent "YOONO is a free downloadable application which includes for the first time search, management and sharing of information. Based on a pooling of user knowledge, YOONO is in the tradition of collaborative services which have started to develop on the web, as shown by the recent launch of Yahoo's MyWeb 2.0. But contrary to tagging systems developped in its time by del.icio.us, YOONO offers indexing of web users' bookmarks to overcome problems of language, synonyms and other syntaq quirks."
I haven't tried it yet but it looks pretty cool. What I like is that they try to solve the problems of launguage and synonyms by indexing the users bookmarks. Will write more later when I have tried it out.
