 As long as we say 'package Foo is the most downloaded package on
CRAN', and not 'package Foo is the most used package for R', we can
leave it to the user to decide if the latter conclusion follows from
the former. In the absence of actual usage data I would think it a
good approximation. Not that I would risk my life on it.

 Pop music charts are now based on download counts, but I wouldn't
believe they represent the songs that are listened to the most times.
Nor would I go so far as to believe they represent the quality of the
songs...

 Should R have a 'Would you like to tell CRAN every time you do
library(foo) so we can do usage counts (no personal data is
transmitted blah blah) ?'? I don't think so....
