Check out the new version of The Conversation Prism 2.0 by JESS3 and Brian Solis and theconversationprism.com. Available as a poster for $20 US on thier website, and they also have some high-resolution versions available.
I love the design of this one. It's seems to be essentially a mind map, but much easier to read and understand.
This is an update to the original Conversation Prism that you can see here on Flickr.
Thanks Dana! I found the link to the 1.0 version on ON:Digital+Marketing
