Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 72% of the 298.1K ratings observed across 4 loaded listings, and the top three hold 100%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 2 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 Utilities — a focused publisher rather than a diversified one.
