For folks that need ideas, think about holiday centered contests to get you started:
Halloween: Scary story, home decoration, best costume, best party planning
Christmas: Story writing, best home decoration, best tree decoration, best family postcard
etc etc

In general, writing humor centered writing contests would generate some attention

I ran a few contests last year; far and away the best responses I had were for the writing contests

I wish I had the focus to run more contests, but they took a lot of my time to run ;>
