Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 60% of the 2,230 ratings observed across 4 loaded listings, and the top three hold 99%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 3 apps account for about 90% of the observed ratings; the rest form a long, light tail. We read that as a strategy signal, not a cadence number: the publisher lists the most apps in Music, yet earns the most ratings in Education — volume and audience sit in different places.
