All eyes are now focuses on the background story behind the acquisition turmoil instagram went through. Not mentioning the new polemical privacy policy story…

Well…. the real story is happening around the app itself. Instagram has recently made a update to the beloved app which is enraging the users. De facto its quality score (the Appsfire App score) has crashed to the lowest level (11, meaning very bad) – down from 97 [a near all time high!]

For the record the App score is a quality score computed every day which is looking at quality signals and parameters like the consistency of the reviews, mentions on twitter, Facebook blogs….

Instagram right now does not have a “ranking” problem: it is still, consistently, a top 25 free app in the US and [...]Read more
