Interesting paper. Casual contributor is very narrowly defined: made 1 (one) commit only. Would be interesting how some slightly less limited definition would change results, or not.
The analysis also excludes all contributions not in the form of commits. Of course including non-commit contributions is hard.
One minor nit: C is characterized as "strongly typed".
