Why do I care? Because I want to allocate the 4-8 hours I have a month to the modules that have the most usage. That's the only reason. It has nothing to do with ego.

There's a difference between usage and install base. ACME::POE::Knee might be installed on a bunch of boxes because people thought it sounded neat and wanted to try it out once, but that doesn't mean it's getting used very often. Other distributions may be installed on fewer boxes, but get used heavily.

Don't get me wrong ... "number of installations" is an interesting metric, but it's not the same as "usage"
