Seems like StackExchange rolled out a new reviewing process - the Community Evaluation review queue today.
While it is a good idea to review those answers to determine the quality of them, there is a varying degree on how we deem an answer to be Excellent, Satisfactory or Needs Improvement.
So the question is: Do we have any basic standards that the various quality answers have? It seems like someone can mark an answer as Excellent and another person may mark it as Satisfactory, and what difference does it make to the reader?
