While I really like the sentiment, I think there's a reason why people naturally don't provide much positive feedback about individuals at workplaces.
What do you really get by pointing out the good work of a coworker? A warm fuzzy feeling, to be sure. Maybe greater comradeship. But wait, who's the next person to get a promotion? Maybe it'll be the person you keep praising to management. So you'll probably have to work smarter/harder to get that same praise, hence the same chances at promotion. But you don't want to work that much harder; you're already working hard enough as it is. But that 5% raise and that "senior" title look pretty shiny. <one year later> Hey, how come nobody has been recognizing you for your good work? Meanwhile that coworker you've been praising is now your boss!
