I have library of resources and links relevant to my customers, in an online mind map on my website.

The mind map is from Mind Meister, which I chose because you have the option of professional looking fonts.

Mind Mup is faster, more dynamic and easier to use, but I chose Mind Meister because MindMup only has either Web 1.0-style fonts, or handwritten or similar novelty fonts, without any clean, modern looking ones.

I won't use MindMup in an outwardly for for any outwardly facing purpose for this reason; the software is incredibly intuitive and easy to run, but cannot generate mind maps that are aesthetically appealling.
