I think people most of us are curious to see the detailed results but I don't think more than a few people would be willing to shell out any $. Perhaps consider opening up the detailed results for this contest as a one-time-thing? I think that the interest+publicity you will receive (in addition to already being #1 on HN) would greatly out-weigh the few hundred bucks that you might get from a handful of people who'd seriously be willing to pay to see these results.
When a post is on top of HN, I don't think we're used to seeing the meat of the content stuck behind a quasi-paywall.
EDIT: It looks like you've posted the results publicly now, nice.
