And here I thought the medium was limited to To Kill a Mockingbird vs. Of Mice and Men.

Pretty interesting:
7. As an innovative way to take notes - I am not sure what the difference is between the "situation" and the "facts" are though. But seeing paradigm as a function of facts + strategy, for instance, was somewhat though provoking

Hmm. A site about venn diagrams that doesn't even mention the terms 'set' or 'subset', let alone the mathematical notation related to them. Maybe I'm missing something, but if I am it's not where it should be. Curious...

How about '1. To aid in the study of set theory' ?

There’s an error in the title. It should be “Top ten ways to use a group of three intersecting circles in ways that look like Venn diagrams but really aren’t”.

I rest my case.

(I still don't see the words 'set theory' anywhere on that site, least of all where they should be. But anyway.)
