What was the rolling stone on gamification?

17 Mar

I was looking through an old blog’o’mine, and found this from way back in the day (Sept. 2006!) , the Google image labeling “game”.
This was my first XP with gamification of social media (to my recollection), but if there are any ideas on bigger/simultaneous rolling stones out there from the mid-2000’s, I’d love to hear them!
