Affinity Diagrams...Sticky Note Heaven

Does anyone besides me have a sticky note obsession? I have some with my name on them, some of them have kittens, some have witty sayings, etc. I never thought I'd be able to put them all to good use. Then I met the affinity diagram. These tools for brainstorming are a sticky note lover's paradise. Here, let me show you.

OK, so the picture isn't super informative. Let me explain the concept. A general topic or question is assigned to a large group of people (these are often used in staff meetings). Each individual writes singular thoughts related to the topic on sticky notes. All the notes are placed randomly on a table or on the wall. Now people attempt to group them based on common themes. In the picture above the columns of yellow notes are the individual ones, the blue notes are the common themes and the, er, single yellow ones (they looked pink before???) unites commonalities between blue groups. And just like that, you have an understanding of the major themes of your topic. YAY!!!
