I whipped up a graph this morning plotting each user with more than 10 comments.
Neil Butterworth wins my world famous "Quality Volume Commentator of the Year" award. Of the top ten commentators, he has the highest average score.
Number of Comments vs Average Score by User alt text http://lanai.dietpizza.ch/images/stack-overflow-comments-user-total-vs-avg-score-small.png
Also, I was looking for odd/interesting relationships between comment scores and whatever. The below graph shows 12 comment score bands versus:
- Average Comment Length
- Average User Id (vaguely, the average age of an account)
- Number of Comments
Note that the left side y-axis is logarithmic.
There most definitely seems to be a relationship between comment length and score--shorter comments score higher. And there is a vague hint that the older SO accounts score higher, but it seems slight.
Any other interpretations? Questions? Comments?
(I've also made an effort to keep these color blind-friendly. Please let me know how I did.)
