Darren Barefoot created a visual called "social media starfish" in his book "Getting to First Base." It was a remix of Scoble's white board. Brian Solis has created the next reiteration - the conversation prism. (Perhaps it inspired this visualization of the Digg Community activity)
The conversation map is a living, breathing representation of Social Media and will evolve as services and conversation channels emerge, fuse, and dissipate.
I'm seeing a remix of the Social Media Game cards. However, the existing "tool cards" have about 3/4 of the tools listed above - but people get so overwhelmed with choices. The holy grail would be a grid that shows prism category, lists the tools, and column that describes possible applications or uses.
