At this point I think it's hard to compete with SO because it's so clear-cut and full of questions and answers for common things.
"Running out of questions." comes to mind.
Also, off-topic, I don't think being in a top percentage is something to brag about or a sign of merit. I've done nothing but ask stupid questions on SO and I was lucky to be there when the site was new (lots of high-coin questions!) and I'm in the top 5%.
That's a good point, but the top 1% (where I expect to be in a year or two) is close to the end of a long tail. Not many people get there by asking questions, and I only started contributing about a year and a half ago.
That percentile rank is a foot in the door in a lot of situations. If someone who is interested in me finds out it's because I give comprehensive smart answers with strong communication, in spite of the fact that I wasn't around when there were lots of easy questions to be had, I think I've got something pretty good to brag about.
That's not to say that I wouldn't consider someone who asks lots of good questions too. That requires communication skills as well as technical skills. I personally find it harder to ask good questions than to give good answers.
