These feel *really* good to get :-) So I've been handing them out like candy. Also useful for when you feel like you're in a battle with someone, and their last edit is just right and you want to say "yep, got it". Whoever thought of this, well done.
Suggestion: enable thanking anonymous editors. Not sure what would be the best way to make it visible to them, but I imagine it would be quite the buzz for them to make that first tentative edit and have someone *thank* them for it.
