I've entered a few Stacks competitions (Jb Hifi) and they post names of winners after entries close etc.
But I think they should really post details of what the exact winning answers are instead of just names of winners. This would show how they really judged the creativeness of entries and how good it really was to be worth a win.
Just my opinion
I hate those 25 words or less competitions.
When I was a young lad I entered a compeition in some local computer magazine. I won some edutainment package for my under 25 words entry. The winner won a computer with a 2 page essay! I was fuming, they broke the rules and still won…wtf.
