The two records

What this comparison does not say

A star count measures attention, not quality, adoption or satisfaction. A repository with fewer stars can be the better tool, and a fast-growing one can be growing for reasons unrelated to merit. Nothing here is a recommendation, and the arithmetic in "which way the gap is moving" is not a prediction.
