Some roles (ops, sales) are just naturally a lot more inclined to use these kinds of systems. I generalize like that after having watched similar systems at 3 companies; you hardly ever see an engineer give a "taco" for a code review, but someone in another team might give one simply for someone knowing which room a meeting is happening in. It's hard to normalize the culture. I think peer bonuses (which usually require manager approval on one or both sides) tend to be a bit more normalized across teams.
