Is it 1+ edits per month, or 3+?
Just in case the answer is 1+. As I explained in mailing lists (and am happy to expound on here) I find it hard to support the idea that a person with just one edit is even called an an editor. Just like a person who writes one word or even sentence per month isn't called a writer. Words lose their meaning if they comprise such fringe cases.
I'm note sure 3+ adds much of a new perspective. We've been consistently using 5+ and 100+ thresholds for so long, without ever much controversy, which says a lot in Wikimedia context ;-)
