When I first discovered GIS SE two years ago, there was a statistic attached to users showing the percentage of questions that they had accepted an answer -- and even criticism lobbed at those with low rates. Am I missing something? Was there a discussion about it?
You can use the Stack Exchange Data Explorer (for GIS-SE)
SELECT PostID [Post Link], CreationDate, UserId, Score, Text FROM Comments WHERE Text like '%accept rate%' ORDER BY CreationDate Desc
