Social scaling and functionality 2
I have posted a similar graphic of mine before, but was focusing the discussion on tagging. I had modified the chart to focus on actions [objects prior] (x axis) from tags to make this shift. Actions in the system are any media being discussed, rating systems, comments, conversations, and essentially any end user contributed content.
Both people participating increase over time (if things work) as do actions.
UPDATE: I updated this image to change Objects in the system to Actions on the left-right axis. Objects has been rather difficult to convey and have clarity of understanding.
