What makes a contributor to Perl?
I'd add in "those who contribute toward a positive perception of the Perl community by being temperate, welcoming, patient, and helpful". You may not believe it, but it makes a huge difference to people who are not "in" one or another of the Perl groups.
Other contributors include those who are graceful when in error. The phrase, "You're absolutely right! Thanks for the correction" makes a big difference too. Insisting that you are technically correct just makes you look like a weasel.
