Oh, you want a Quest, not a goal. :-) In that case, try writing an article that says exactly the opposite of something that somebody with very high (>10,000) karma says, even linking to their statement to make the contrast clear. Bonus points if you end up getting into a civil conversation directly with that person in the comments of your article. Note: I believe that it is not only possible, but even easy, for you to do this and get a net karma gain. All you need is (a) a fairly good argument, and (b) a friendly tone.
