If you look at our about page, you will see an example question about unicorns (which is a frequently used meme / joke on meta).

However, if you look at eg Sci-fi you will see that its about page contains a real example question for its site.

Why is that?

At first glance, it might not seem like a big deal. But a first time user (the target audience for the about page) would be forgiven for thinking this is a joke site.
