Yesterday morning, I mention that it's Surprise that makes viral videos viral.
Yesterday afternoon, I get this Holiday Card from Twist Image, that encapsulates the year in--you guessed it!--viral videos.
Follow it through, see how many you sent and/or received throughout 2006...
...then let my point sink in even deeper.
(By the way, the Twist Image card itself became somewhat of a viral phenomenon, finding its way around the web faster than a speeding Line Rider.)
