BETA MINDMUP provides mind-mapping capabilities with a twist. Besides being ridiculously easy to use and share (via email, Twitter, Google+, Facebook, Reddit, Evernote, LinkedIn, Pinterest, and URL link at last count), the web-based tool is also completely open source. That means an unlimited volunteer army of developers "implementing all the tweaks and changes" that users submit via feedback, and hopefully a much quicker path to the founding team's dream of "zero-friction" mind-mapping.
