I came across this, and it made my mind hurt. Take a look:

The Website Marketing Mind Map: Internet Marketing Made Easy

Here's what Godin had to say abt it: The power of chunking

Do you agree with his rule of 3?

Soul's Law: The Magic of Three (been quoting it for several decades now)..  ironically, a full description requires more that Godin's three bullet points but here goes anyhow:

• 1 example  says nothing about about anything .... there's no context to 'manage' the single thought
• 2 examples will usually highlight differences and not usually lead to real learning
• 3 examples is the minimum needed to show both differences and similarities and give a modicum of context for learning

hmmmm.... very similar to  my essay writing system

I think the chunking suggestion of three is worth paying attention to. The power of that mind map is being able to see the entire context of the topic. The MInd Map could likely have been chunked down further.
