I'm not entirely sure what is used, number of editors or number of visitors, or even number of page views, but it's definitely not the number of articles. Using the article count as a measure of a wiki's success or popularity is not terribly accurate because some wikis choose to contain more information within the single article. Some wikis also import large amounts of info from elsewhere. I'm sure Children's Books doesn't do that, though. :)

Whatever the real approach to deciding the Top 10 is, continuing to build content is key to success - and some tricks like this can be thrown in from time to time.
