It already exists, in places. You’ve probably written a review for private businesses, but how many commendations have you submitted to your transit worker, city service worker or politician?

You can file compliments in the same place you file complaints, via phone, paper form, web form, e-mail or snail-mail. I’m sure these people would be pleasantly surprised to receive your positive feedback.

Commendations are brought to supervisors, and sometimes they even make the agency’s public newsletter. They cost nothing but a bit of time and thoughtfulness to give, so I’d say give it a try.
