Of course, Quiz Planet is by one of Playdom’s major rivals, CrowdStar. Note that CrowdStar also has its games Happy Pets and Happy Aquarium on the list, while its new title It Girl appears to be taking off; it’s possible that CrowdStar is doing an across-the-board push for all of its apps. We’ll look more deeply into the games this morning over at Inside Social Games.

Celebrity Birthdays comes up in third place with a gain of almost a million new MAU. The app looks to have ended its practice of auto-posting to user’s walls, which we noted last year, and has begun monetizing with LifeStreet ads at the top.

Friend Facts™, at number four, is the latest friend quiz to appear; further down, Phrases has just become the third-largest app on Facebook by MAU, with user-generated quizzes and quote collections in multiple languages.

The last app we’ll point out is BandPage by RootMusic, which is trying to create a customizable MySpace-style experience for bands on Facebook. After we profiled BandPage in early August, its MAU growth flattened out, but now it appears to be on its way up again.
