What happened to typing your appreciation? Why do we need extra commendations. Communicate!

I think it's fine as it is now: optional and can be used for little things in game. SE should never give big rewards for commendation currency. It will ruin its purpose.

If anything, I'd fancy the opposite of commendations. As people already mentioned, sometimes people have no clue about either the content or their job. Not the worst thing, but then they don't communicate. I think communication is key in an MMO.
