I just came across a site called MindMeister, which is a web based mind mapping/brainstorming software. It is similar to mywebspiration.com (which is currently in beta and free, but will likely be available as a paid subscription only soon) and is free for up to three boards, or if you are in education you can get the Premium edition for only $18/year. My initial thoughts on this site are very positive. The free version allows for the basics (create a board, sharing, printing, exporting to a pdf, etc…), but for $18 a year there are some additional very cool features. There is really too much for me to mention in a blog post, so check it out for yourself at http://www.mindmeister.com/. Another big plus for me is the ability to work in offline mode if you are traveling and do not have access to email and the mobile app.
