I made a mindmap of Getting Real

I am obsessed by mindmaps: I do them for many things I read (books or articles) to summarize them and be able to come back to it later, in order to strength the knowledge I acquired.

A mindmap is very visual: you can hide the part you don't want to see and only review what you want to review.

It works pretty well to really study and learn many things (by reviewing the mindmaps often), not only reading stuff and forgetting afterward. You can create flashcards from them as well, for example.

I have right now 124 mindmaps in what I call my "knowledge base", which is awesome.

As an example, here's the mindmap for Getting Real I finished last week. You can open it using the free software freemind. It took me a bit more than two hours to do it.

I could give away every single one of them, but I think mindmaps should be something personal : you learn a lot while doing them and the way you do it should reflect how you learn and what you want to learn.

Some weeks ago, I had the idea to build a whole mindmap system which could be used as a second brain. I thought about:

• Plain text mindmap based on markdown, with metadata to describes the nodes / possible links or descriptions attached to them.
• Creating an UI to edit them easily.
• Possibility to links mindmaps together to create layers of mindmaps.

This would be the MVP. Then I have other ideas:

• Possibility to import mindmaps from Freemind.
• App for Android and Iphone.

I think it would be open source at first, with a payed version to synchronize the mindmaps. I know it's a lot of works, but I'm really interested by the idea.

What do you think? Do you know anybody (communities, professions...) which could be interested?
