Publishing behaviour

The catalogue’s attention is unevenly distributed. The single most-rated app holds 100% of the 1.7M ratings observed across 7 loaded listings, and the top three hold 100%. That is a portfolio led by a small flagship set rather than an even bench.

Roughly 1 app 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 Business — a focused publisher rather than a diversified one.
