Vic Gee runs the Mind-mapping.Org web site and has catalogued every mind- and visual mapping software tool there is - 377 if I have read Vic's summary correctly.
Just launched is a new site that takes the catalogue and helps users find the most relevant tools quickly. In addition they can log their own experience of each software tool and provide a star rating. As this builds up it will provide a unique insight into "what's hot and what's not" in the world of mind mapping. The presentation is stunning.
Vic has provided a brief introduction to the site at his blog - see "Vic's Picks is here!"
