If you see a question on Facebook or Twitter (and you know the answer) odds are you will reply with the answer.
You’re not looking for points, rewards, or some other incentive, you simply want to help (and maybe feel smart).
In fact, out of every factor we’ve ever looked at, seeing questions you know the answer to is by far the bigger determining factor in whether someone will participate in the community.
It’s easy to get hooked up developing gamification programs, superuser programs, trying to build a powerful sense of community, creating onboarding journeys etc. But the biggest bang for your buck is usually improving question visibility.
How do you get more questions in front of more people who might know the answer?
First improve the site design, notifications (and digests), and improve the notification systems. Then look at everything else.
