Valid points against the idea. Well, I haven't tried it out myself, but just got the idea as I read this topic.
Anyways, to offer clarity to Planet13, what I meant was initiating a discussion on your blog (Eg: Why the air operation against Osama was wrong) and asking for your readers to provide valid counter points on their own blogs. Since these blog posts are responses to the original argument on your website, these bloggers would inevitably link to your site from theirs. And you may pick the best of the lot and offer them freebies using the $100 budget.
But yes, it is not always that you have so many readers who have their own websites. Also, you could end up antagonizing at least a few of them by announcing a winner.
