I read a good post from Dan Pink about the workplace is a desert when it comes to feedback. Well worth reading the full article (here: http://bit.ly/eaUVI7 ). Not dissing the level of feedback at SaskTel; we have several programs like he recommends, but it's a good reminder.
Dan's article reminds me of two cool TED videos on gaming culture and how feedback from games can be used for good. There's a connection here, I can feel it!
