We are looking for a mindmap tool supporting web-based concurrent editing. The purpose is to capture a team discussion during problem resolution and to visualize it (mindmap). It should also be possible for persons outside the team to follow the discussion by subscribing to a discussion feed (a la twitter/yammer), and also be open for them to comment on the discussion.
Does anyone know of a tool supporting the above, or set of components that could be integrated to support it?
Mindmeister and Mindomo can do that. They're the only two I can think of off hand.
Mindmeister also has the advantage of keeping track of changes - what and by whom - and allows reversing changes. Mindomo may do that as well. Are there any Mindomo users who can fill in?
And does anyone know any other on-line mind mapping software that handles multi-user simultaneous updating?
