Mostly I wanted to make sure the domain didn't fall into the hands of a squatter. I know that a lot of us have ideas that we work on as side projects, but haven't made the jump from our dev machines and into the "real world".
Luckily I got it contact with a few people who are at that state, so the domain will go to one of them.
As a side note, while a contest would be a lot of fun, I'm busy now growing my own startup and can't imagine how insanely jam-packed my days will be 6 months from now following this growth curve.
