I would say that the important issue is to have the detailed data. If
for some person (or company) it is important to count lines of code, or
commits, or closed tickets, or whatever, you can go for it and that's
all. Data is just data: you can mine it for the answers to your own
This said, I also agree with Thierry in that "highlighting" important
aspects for the project can only help. That can be used to put some
"social pressure" on users of the software, as he suggests. That may
also be used to highlight who is contributing the most (as Stefano said,
it may be useful to know which companies are engaging more with the
project, and in some cases that's clear by almost any metric. Or to
track the time-to-review per project. Or to show open tickets over time.
My impression is that we still need some time to learn which metrics are
interesting enough to visualize them. And contribution metrics are a
part of them.
