Why is the Al Jazeera app not showing up on App store Top 25?

Slightly curious as to why the Al Jazeera app isn't showing up on the App Store top 25. If you haven't checked the app out already, it's great - free live-streaming video of Al Jazeera English.

Before I went to bad last night it had around 1400 reviews, with an average rating of four stars.

Today the review-count has been reset (build status says a new build was pushed out yesterday but I wasn't prompted for an update. weird)

Also, quite a few reviews of the app seem dubious. Try reading the 1 star reviews.

Wouldn't be surprised if Apple's invisible hand is somehow involved with this.
