That gives contestants that won from January to June multiple opportunities to participate in one given year and the people from July to December only 1 chance that same year. For instance, the winner of January can go at it again after July but the person who wins in in July cannot play again that year.
Every time I've skimmed over this it makes me pause, because none of us think of it as "playing" and, looking over the list, I'm fairly certain none of us do what we do with any thought of this contest in mind. We don't choose to participate. Members nominate us. We can choose to opt out, but not in.
I've always viewed my nominations as proof that I must have been doing what I came here to do and an encouragement to work even harder to advance the causes we find on these digital streets. I can tell you I have never voted for myself. There are some who view this as a popularity contest and I believe they missed the entire idea behind the honor. We're here to serve, and we really ask nothing in return. This honor humbles you in a way that I assume surprised almost every past recipient as much as it did me.
And go Mr Am4zin!
