There's an easy way to weed out unlucky people. Just randomly throw out half the applicants. (You can substitute any proportion for "half" based on business needs)

You might say it's useless (in your blog post) but would it surprise you to know that there's a venture funded startup doing pretty much what your weekend project does (with extra bells and whistles perhaps).
