Out of date cache makes sense although I don’t think I’ve seen any system app ever above 3 stars (that’s why I even checked the Playstore page). Deleting the comment to not further propagate my false assumptions.

(Edit: There were two screenshots here, showing wildly different ratings for the app on the DuckDuckGo results page and the Playstore itself. The comment below kindly reminded me that DDG doesn’t update in real time. Duh. I apologise for posting too quickly.)

MySpace was way smaller than Facebook, it wasn’t even available where I am for most of its (meaningful) existence (I never had a MySpace despite being the exact target age range).
