When I was making a Venn diagram to show the overlap in how I use Instagram, Facebook and Flickr, I had the idea to create a few basic blank models. David Sparks regularly shares how he diagrams everything, often during a meeting with a client. So my thought process was to have a few stock diagrams that I could pull from instead of starting from scratch each time.

While Omnigraffle is a powerful app to quickly build diagrams, I wanted something a little less profession and a little more playful. So I drew the diagram in Paper and then added words in Omnigraffle.

I had so much fun creating the Venn,

that I had to create a two-by-two grid,

and, of course, a bell curve.
