When it was released 224 days ago (http://news.ycombinator.com/item?id=1870473), I remember this "mimics your brain" idea but it never bothered me. I did not feel invited to compare it to mind-mapping products. I took Workflowy as a nice dynamic lists software. I like it because of that. It really helps. It was made with the principle that Almost everything you create on Google Docs is a list, so they made Workflowy[1].
I also find mind-mapping studies fascinating. Many times I find myself starting to write in the middle of a sheet of paper and then making connections. I know this is not Workflowy. Can you give some good suggestions on mind-mapping software?
