Nominations for the Christmas give-away entry number 3!
Stack Exchange isn't just about questions and answers, who has contributed the most to the community?
I nominate @joan for an incredible amount of high-quality answers given and an even more tremendous quantity of comments to inquire additional info and provide clarification. (... and also for pigpio).
I would like to nominate @Ghanima. He very clearly cares about this site; to the point where he's willing to run as a moderator. That speaks volumes to his commitment.
