I have a co-worker who is also a user of Stack Overflow. (Web programmer). Today I noticed a question on SO that I knew he'd be able to answer as we do it all the time here. I emailed him the link, he answered it off the top of his head... boom bam easy.
I then joked it was too bad SO didn't have an "assist" badge like in the NBA when one player passes the ball to another who then scores. There would need to be a mechanism to link the assist to the answer in the link... but seems trivial.
You would have to decide if its an internal or external pass/track mechanism.
I would probably lean towards an external process as it ensures that links are shared between users who know each other outside of SO. Shooting from the hip SO has the link share feature and tracks who created the link. So, if another user who accessed the question via your link answers the question that's accepted... it's an assist.
If it were an internal tracking process I could forsee 10k+ users getting bombarded by questions from those hunting the badge.
As for naming: Assist for the bronze level. "Pippen" for the silver version (famous assist man for Jordan). Finally Stockton all time NBA assist leader as the gold level.
It meets the purpose of SO badges... encourages good usage of the site and is fun.
Update Edit - it could easily lose the NBA reference while retaining the point of the badge. It was just the NBA assist stat that made me think of it.
