Publishing behaviour
The catalogue’s attention is unevenly distributed. The single most-rated app holds 26% of the 911 ratings observed across 27 loaded listings, and the top three hold 60%. That is a portfolio led by a small flagship set rather than an even bench.
Roughly 12 apps account for about 90% of the observed ratings; the rest form a long, light tail. Both the largest cluster of apps and the bulk of the ratings sit in Lifestyle — a focused publisher rather than a diversified one.
