As long as we're being pedantic...

It says the best (presumably "most effective") way to get the right answer is to post the wrong one. That doesn't mean that posting the wrong one will always work; it might be that if posting the wrong answer fails, there was no way to get the right answer, or that the successful ways would have been more effort than they were worth. (Obviously, this isn't true.)

> Another way to disprove it is not the best way. Now that they told you this "secret" next time you have a question will you post a wrong answer or find the right place and try to formulate the question as best as you can?

This doesn't disprove Cunningham's law, any more than people failing to wash their hands disproves germ theory. And even if Cunningham's law is true, posting the wrong answer in order to get the right one is rude.
