I've been using this free mind mapping service at http://bubbl.us/ but now it looks like they are switching over to a paid subscription. NOTE: free accounts get 3 maps, lol. It's only $6/month, but I'd like to see if there is something else out there. It's such a simple concept of an application but I just like the layout and how clean it is. Not sure if I want to spend $72/year on it though. Does anybody here know of a good alternative? The other mindmap programs I could find in Google, to be honest, look like crap.
